Essential oils of seven Musa spp.’s fruits namely, Musa acuminata colla ‘gros michel’ (PE), Musa acuminata colla ‘lakatan’ (PB), Musa acuminata colla ‘sucrier’ (PM), Musa acuminata × balbisiana ‘horn plantain’ (PT), Musa acuminata × balbisiana colla ‘saba’ (PN), Musa acuminata colla 'inarnibal' (PO) and Musa acuminata colla ‘red’ (PJ) were extracted by hydrodistillation method using Clevenger apparatus. The essential oils were analysed using GC-FID and identified using Kovat Indeces compared with published information. PE gave the highest yields of oils compared to the other species with yield of 0.43% and 0.28% for its peels and flesh, respectively. The most abundant groups present in most of the essential oils are ester and alcohol groups. The brine shrimp toxicity of PT, PM, PN and PO essential oils were tested and showed toxicity against brine shrimp in dose dependent manner. It can be concluded that the essential oils showed some biological activities which may be a potent medicine in curing tumor. This study implies that the presence of ester and alcohol groups are a good marker for the biological activities of plants. Further studies should focus on the potential of the essential oils of Musa spp. as an antitumor medicine.

This study intends to discuss the mechanism of MTH1 inhibitor (TH588) in the biological activity of ovarian carcinoma cells. A2780 and SKOV-3 cells were treated with different concentrations of TH588 and assigned into AT group (control), BT group (8 μmol/L TH588), CT group (16 μmol/L), DT group (32 μmol/L), ET group (64 μmol/L) and FT group (128 μmol/L) followed by measuring level of Bcl-2 and Bax by Western blot and PCR, and cell biological activities by MTT, FCM and Transwell chamber assay. The cell proliferative rate was not affected in AT group, but was lower in other groups in a reverse dose-dependent manner. There was significant difference on apoptotic rate and cell invasion among groups with increased apoptosis and reduce invasion after TH588 treatment. FT group showed lowest expression of Bcl-2 and Bax compared to other groups. In conclusion, the biological activity of A2780/SKOV3 cells could be reduced by MTH1 inhibitor which was probably through regulation of Bax and Bcl-2 expression.

We performed partial purification of low molecular weight luteinizing hormone binding inhibitor from porcine follicular fluids and examined its biological activities. Following ultrafiltration, gel filtration and anion exchange of the pooled porcine follicular fluids, low molecular weight fractions (500–10,000 MW) inhibited [125I]hLH binding to porcine granulosa cells in a dose-dependent manner. The binding inhibition kinetics study revealed that the luteinizing hormone binding inhibitor may indicate a non-competitive inhibition with [125I]hLH binding. In vitro bioassay using adult mouse testicular interstitial cells revealed that the partially purified luteinizing hormone binding inhibitor reduced ovine LH-stimulated testosterone and cAMP production in a dose-dependent manner, whereas the luteinizing hormone binding inhibitor did not affect basal production of testosterone and cAMP. The inhibitory activity was heat stable and did not disappear with activated charcoal adsorption. The results of the present study suggest that the luteinizing hormone binding inhibitor may play an important role as an ovarian non-steroidal regulator modulating the receptor binding of LH and LH-mediated steroidogenesis.

Background: Interleukin-6 (IL-6) is a multifunctional cytokine involved in various cell functions and diseases. Thus far, several IL-6 inhibitors, such as, humanized monoclonal antibody have been used to block excessive IL-6 signaling causing autoimmune and inflammatory diseases. However, anti-IL-6 and anti-IL-6 receptor monoclonal antibodies have some clinical disadvantages, such as a high cost, unfavorable injection route, and tendency to mask infectious diseases. While a small-molecule IL-6 inhibitor would help mitigate these issues, none are currently available. Objective: The present study evaluated the biological activities of identified compounds on IL-6 stimulus. Methods: We virtually screened potential IL-6 binders from a compound library using INTerprotein’s Engine for New Drug Design (INTENDD®) followed by the identification of more potent IL-6 binders with artificial intelligence (AI)-guided INTENDD®. The biological activities of the identified compounds were assessed with the IL-6-dependent cell line 7TD1. Results: The compounds showed the suppression of IL-6-dependent cell growth in a dose-dependent manner. Furthermore, the identified compound inhibited expression of IL-6-induced phosphorylation of signal transducer and activator of transcription 3 in a dose-dependent manner. Conclusion: Our screening compound demonstrated an inhibitory effect on IL-6 stimulus. These findings may serve as a basis for the further development of small-molecule IL-6 inhibitors.

Four essential oils from the leaf (P23) and rhizomes (P19, P22, P24) of Acorus calamus L., collected from various parts of Nepal, were obtained by hydrodistillation and analyzed by GC-MS. From a total of 61 peaks, 57 compounds were identified among the four essential oils accounting for 94.3%, 96.2%, 97.6%, and 94.1% of the oils, respectively. All of the essential oils were dominated by ( Z)-asarone (78.1%–86.9%). The essential oils also contained ( E)-asarone (1.9%–9.9%) and small amounts of γ-asarone (2.0–2.3%), ( Z)-methyl isoeugenol (1.5–2.0%), and linalool (0.2–4.3%). Allelopathic testing of the rhizome oil showed inhibition of seed germination of Lactuca sativa and Lolium perenne with IC50 values of 450 and 737 μg/mL, respectively. The rhizome essential oil demonstrated stronger seedling growth inhibition of L. perenne than of L. sativa, however. The rhizome oil also showed notable brine shrimp lethality ( LC50 = 9.48 μg/mL), cytotoxic activity (92.2% kill on MCF-7 cells at 100 μg/mL), and antifungal activity against Aspergillus niger (MIC = 19.5 μg/mL).

Background: Polyalthia simiarum (Hook. F. &Thomson) exhibits different effects in human body. Objective: As a part of ongoing research on medicinal plants of Bangladesh, the present study is focused to investigate the analgesic and anti-inflammatory activities of stem bark of Polyalthia simiarum (Annonaceae). Methodology: The ethyl acetate (EA) and petroleum ether (PE) extracts were subjected to qualitative chemical investigation for the identification of different phytoconstituents. The analgesic activity was determined for its central and peripheral pharmacological actions using tail immersion method and acetic acid-induced writhing test. The anti-inflammatory activity was evaluated by carrageenan induced paw edema in rats. Analgesic and anti-inflammatory data were evaluated statistically analysed by Dunnett’s-T test. Result: Both extracts at the dose of 50- and 100 mg/kg b.w., produced significant increase in pain threshold in tail immersion method whereas significantly reduced the writhing caused by acetic acid in a dose dependent manner. The EA and PE extracts showed anti-inflammatory activities at 50- and 100 mg/kg body weight. Among all the extracts, the EA extract showed a dose dependent and comparable analgesic activity in all the tested methods and also reduced the paw edema considerably (27.5% and 39.1% inhibition after 4h), in dose dependent manner when compared to carrageenan induced control rat. Conclusion: Therefore, the EA and PE extracts of Polyalthia simiarum were capable to exhibit moderate analgesic and anti-inflammatory activities. This is the first report of analgesic and anti-inflammatory potential of Polyalthia simiarum and can be further investigated to isolate the active compounds responsible for the biological activities.

Tubers of Corydalis cava were extracted with ethanol and fractionated using n-hexane, chloroform and ethanol. Repeated column chromatography, preparative TLC and crystallization led to the isolation of fifteen isoquinoline alkaloids. The chemical structures of the isolated compounds were determined on the basis of spectroscopic techniques and by comparison with literature data. All isolated compounds were tested for human blood acetylcholinesterase (HuAChE) and human plasma butyrylcholinesterase (HuBuChE) inhibitory activity. (+)-Canadaline inhibited acetylcholinesterase as well as butyrylcholinesterase in a dose-dependent manner with IC50 values of 20.1 ± 1.1 μM and 85.2 ± 3.2 μM, respectively. (+)-Canadine, with an IC50 value of 12.4 ± 0.9 μM, was the most potent inhibitor of acetylcholinesterase, whilst (±)-corycavidine and (+)-bulbocapnine were effective inhibitors of butyrylcholinesterase with IC50 values of 46.2 ± 2.4 uM and 67.0 ± 2.1 μM, respectively. The other isolated alkaloids were considered inactive (IC50 > 100 μM).

The present study was carried out to investigate the possible analgesic, neuropharmacological and cytotoxic activities of the methanolic extract of Trigonella foenum-graecum Linn. leaves. The analgesic and neuropharmacological activities of Trigonella foenum-graecum Linn. were investigated at the doses of 100mg/kg, 200mg/kg and 400mg/kg of body weight in mice. Analgesic potential of the extract was evaluated for centrally acting analgesic property using tail immersion method and peripheral analgesic actions using acetic acid-induced writhing test. In acetic acid-induced writhing test, extract produced a significant (p < 0.001) inhibition of writhing response in a dose dependent manner but maximum inhibition (93.46%) of writhing was found at 400mg/kg dose. In tail immersion method, extract caused a significant (p < 0.001) increase in latency time and the results were comparable to the standard drug Diclofenac- Sodium. In addition, neuropharmacological property of crude extract was carried out by Hole cross and Open field test. The extract significantly (p < 0.05-0.001) displayed a dose dependent suppression of motor activity, exploratory behaviour. Furthermore, the extract was subjected to Brine Shrimp lethality bioassay for primary evaluation of cytotoxicity, where the extract was found to be highly toxic to Brine Shrimp nauplii, having LC50 values of 10μg/ml while the LC50 of the reference anticancer drug vincristine sulphate was 0.66μg/ml. The results of this present study suggest that the extract possesses analgesic, cytotoxic and CNS depressant activities. Key Words: Trigonella foenum-graecum Linn.; cytotoxicity; neuropharmacological; analgesic activity.

In this paper antinociceptive and anti-edematous effects are examined of the essential oils of the underground parts of two Balkan endemic Laserpitium species (Apiaceae), L. zernyi and L. ochridanum. Furthermore, the essential oil of the underground parts of L. ochridanum is chemically characterised by GC and GC-MS. Antinociceptive and anti-edematous effects were measured in a rat model of localized inflammation, induced by carrageenan, using apparatus for the modified paw-pressure test, and plethysmometer, respectively. The effects of both Laserpitium essential oils were measured after oral gavage administration to male Wistar rats in doses of 25, 50 and 100 mg/kg. The main constituents of L. ochridanum essential oil were: α-pinene (33.2%), α-bisabolol (10.3%) and chamazulene (14.9%). The essential oil of L. zernyi was previously shown to be rich in α-pinene (31.6%) and α-bisabolol (30.9%). Both examined essential oils produced a significant dose-dependent antinociceptive effect. The corresponding ED50±SEM in producing antinociception were 45.9±4.9 mg/kg and 42.4±2.1 mg/kg for L. zernyi and L. ochridanum oil, respectively. Both essential oils also significantly reduced paw edema in a dose-dependent manner. The estimated ED50±SEM values for the anti-edematous effect were 36.3±4.5 mg/kg for L. zernyi oil and 45.1±11.3 mg/kg for L. ochridanum oil. These results suggest that the essential oils of both investigated Laserpitium species may be effective against pain and edema present in various inflammatory conditions.

Glycosaminoglycans (GAGs) are long unbranched polysaccharide that composed of repeating disaccharide units. They are classified into heparan sulfate (HS), heparin, chondroitin sulfate (CS), dermatan sulfate (DS), keratan sulfate (KS) and hyaluronic acid (HA). During the last decade, demand of GAGs were getting increased due to their potential uses. Vertebrate animal, commonly cartilaginous mammalian tissue, were potential producer of GAGs and have the higher number of biological activities extracted from sea bass waste. Sea bass waste from Lates calcarifer was used as the raw material to extract crude GAGs. Different part of sea bass waste such as, gills, viscera and air bladders were used. The higher content of crude GAGs in sea bass waste was used in cytotoxic and inflammatory study. Different concentration of extract GAGs from gills were used ranging between 0.16-20 mg/mL. GAGs from sea bass waste (gills) showed dose-dependent cytotoxic activity towards MCF-7 cell line in lower concentration. Meanwhile, for anti-inflammatory study GAGs from sea bass waste (gills) showed dose-dependent manner and also reduce NO production in LPS-stimulated cells. This research study concluded that, GAGs from sea bass waste are the alternative source that can be used for cancer and inflammation study.

The chemical compositions, antimicrobial activities, antioxidant activities and cytotoxicities of the essential oils isolated from the root of Kadsura longepedunculata Finet et Gagnep (KLREO) and the fruit of Schisandra sphenanthera Rehd. et Wills. (SSFEO) were investigated.The analyses of gas chromatography-mass spectrometry (GC-MS) showed that cadinane type compounds and their derivatives were rich in both oils (54.2% and 39.7%, respectively) and δ-cadinene was the major component of both oils (13.8% and 25.6%, respectively). The antimicrobial activities of both oils were evaluated against five microorganisms with the disc diffusion and the broth micro-dilution method. Results showed that Gram-positive bacteria were more sensitive to both oils than Gram-negative bacteria and the yeast. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the oil of KLREO were lower than those of SSFEO, indicating that the former possessed slightly stronger antibacterial capability than the latter. The reducing power and lipid peroxidation assays were employed to study the potential antioxidant activities of both oils. Both oils remarkably decreased the content of malondialdehyde (MDA) in rat liver homogenate in a dose dependent manner. The antioxidant activities of KLREO appeared to be more potent than that of SSFEO. The oils of KLREO and SSFEO exhibited concentration-dependent cytotoxicities and were proved to be toxic to HepG2 cells with IC50 of 147 and 189 μg/ml, respectively.
