Thrombotic disorders like myocardial and cerebral infarction are fatal blood clotting related diseases. Synthetic therapeutics used in such disorders has serious adverse effects, so there is a need to investigate some more safe natural thrombolytic agents. Present study is a preliminary work towards such endeavors. During this study analysis of thrombolytic activity and anti-inflammatory activity of Thespesia populnea leaf extract using a simple and quick in vitro clot lysis assay was performed. Various concentrations of leaf extract i.e. 200μg/ml; 400μg/ml and 600μg/ml were tested at various time intervals including; 24, 48 and 72 hours duration of incubation at 37°C for observing maximum clot lysis. The result findings indicated that concentrations of leaf extract enhanced the percentage of clot lysis in dose dependent manner along with the incubation time factor. However; streptokinase SK a reference standard and water were used as a positive and negative control showed clot lysis maximum 96.35% and 35.22% in 72 hours of incubation respectively. Alcohol extract of whole plant of Thespesia populnea (Family: Malvaceae) was assessed for its anti-inflammatory activity by in vitro methods. In vitro anti-inflammatory activity was evaluated using albumin denaturation assay at different concentrations. Diclofenac sodium was used as standard drug. The results showed that Thespesia populnea alcohol extract at a concentration range of 400-1600μl significantly protects from protein denaturation.

Sugarcane bagasse (Saccharum officinarum L) is a readily available waste product of cane sugar processing. The content of lignocelluloses in sugarcane bagasse is approximately 52.7% cellulose, 20% hemicelluloses, and 24.2% lignin. Lignin can be degraded enzymatically by using microorganisms, such as Ochrobactrum sp. Monomer derived from lignin degradation using these bacteria in the optimum condition of sugarcane fermentation (pH 6, temperature 40 °C, for 5 days of incubation, the concentrations of starter 29%) by GC-MS yielded phenolic compounds such as 4-methyl-2, 6-di-tert-butylphenol; 2,6-di-tert-butylquinone; phenol, and p-hydroxybenzaldehide. The thrombolytic activity of these lignin monomers can be tested in-vitro by measuring the ability of clot lysis. Lignin did not have in-vitro clot lysis activity, whereas the lignin monomers in filtrat of fermented sugarcane bagasse have an in-vitro clot lysis activity, although its capacity is not as high as streptokinase.

Syzygium fruticosum (SF), a valuable Bangladeshi fruit, is considered an alternative therapeutic agent. Mainly, seeds are used as nutritional phytotherapy to ease physical and mental status by preventing chronic diseases. Here, we scrutinized the S. fruticosum seed’s fundamental importance in traditional medicine by following an integrated approach combining in vivo, in vitro, and in silico studies. The SF was fractionated with different solvents, and the ethyl acetate fraction of SF (EaF-SF) was further studied. Mice treated with EaF-SF (200 and 400 mg/kg) manifested anxiolysis evidenced by higher exploration in elevated plus maze and hole board tests. Similarly, a dose-dependent drop of immobility time in a forced swimming test ensured significant anti-depressant activity. Moreover, higher dose treatment exposed reduced exploratory behaviour resembling decreased movement and prolonged sleeping latency with a quick onset of sleep during the open field and thiopental-induced sleeping tests, respectively. In parallel, EaF-SF significantly (p < 0.001) and dose-dependently suppressed acetic acid and formalin-induced pain in mice. Also, a noteworthy anti-inflammatory activity and a substantial (p < 0.01) clot lysis activity (thrombolytic) was observed. Gas chromatography-mass spectrometry (GC–MS) analysis resulted in 49 bioactive compounds. Among them, 12 bioactive compounds with Lipinski’s rule and safety confirmation showed strong binding affinity (molecular docking) against the receptors of each model used. To conclude, the S. fruticosum seed is a prospective source of health-promoting effects that can be an excellent candidate for preventing degenerative diseases.

Abstract Background Brassica nigra is a plant of Brassicaceae family, which possesses numerous medicinal values. Our present study is intended to assess the potential in vitro thrombolytic, anthelminthic, cytotoxic and in vivo anxiolytic properties of MCE of B. nigra flowers. MCE was fractioned for separating the compound on the basis of polarity by using chloroform, n-hexane and ethyl acetate solvent. Thrombolytic and anthelminthic activities were explained by collecting human erythrocytes and earthworms as test models, respectively. Anxiolytic activity was evaluated by elevated plus maze and hole board models while cytotoxic test was conducted through brine shrimp lethality bioassay. Results MCE revealed the presence of alkaloids, flavonoids, tannin, diterpenes, glycosides, carbohydrates, phenols, fixed oils and fat. In case of thrombolytic test, the MCE, CSF, ASF and n-HSF had produced maximum clot lysis activity at 5 and 10 mg/ml dose conditions. Two different concentrations (10 and 20 mg/ml) of MCE and its fractions showed significant (p < 0.05) anthelminthic activities in a dose-dependent manner. Significant anxiolytic activity was observed for all fractions which was comparable to the standard drug diazepam (p < 0.05). Again, the cytotoxic screening also presented good potentials for all fractions. Conclusion From the findings of present study, we can conclude that MCE of B. nigra flowers and its fraction possess significant anxiolytic, anthelmintic, anticancer and thrombolytic properties which may be a good candidate for treating these diseases through the determination of bio-active lead compounds.

Fibrinolytic enzymes have received more attention due to their medicinal potential for thrombolytic diseases. The aim of this study is to characterize the in vitro fibrinolytic nature of purified protease producing Streptomyces radiopugnans VITSD8 from marine brown tube sponges Agelas conifera. Three varieties of sponge were collected from the Rameshwaram Sea coast, Tamil Nadu, India. The fibrinolytic activity of Streptomyces sp. was screened and determined by casein plasminogen plate and fibrin plate methods respectively. The crude caseinolytic protease was purified using ammonium sulfate fractionation, affinity and ion-exchange chromatography. Based on the morphological, biochemical, and molecular characterization, the isolate VITSD8 was confirmed as Streptomyces radiopugnans. Maltose and peptone were found to be the best carbon and nitrogen sources for the production of fibrinolytic protease. The carbon and nitrogen source peptone showed (781 U/mL) enzyme activity. The optimum pH and temperature for fibrinolytic protease production was found to be 7.0 and 33 °C respectively. The purified enzyme showed a maximum specific activity of 3891 U. The blood clot lysis activity was compared with the standard, and it was concluded that a minimum of 0.18 U (10 µL) of purified protease was required to dissolve the blood clot. This is the first report which exploits the fibrinolytic protease activity of Streptomyces radiopugnans VITSD8 extracted from a marine sponge. Hence the investigation suggests a potential benefit of purified fibrinolytic protease which will serve as an excellent clot buster alternative.

Abstract Background Campsis radicans L. is a flowering plant in Bangladesh, traditionally used for the treatment of several human diseases. In this study, in vitro antioxidant, thrombolytic, membrane stabilizing and in vivo analgesic, hypoglycemic, anti-diarrheal and CNS antidepressant activities of organic soluble fractions of crude methanol extract of C. radicans leaf were investigated using appropriate experimental models. Methods The leaves of C. radicans were collected, authenticated, dried and extracted with methanol at room temperature for 30 days. The concentrated methanol extract was partitioned to petroleum-ether (PESF), dichloromethane (DMSF) and ethyl acetate (EASF) soluble fractions. The antioxidant activity of these fractions was determined by DPPH free radical scavenging method. Total phenolic content was determined by the Folin-Ciocalteau’s spectrophotometric method. The thrombolytic activity was assessed by measuring clot lysis ability whereas the membrane stabilizing activity was evaluated by heat- and hypotonic solution-induced hemolysis assay. Tail immersion procedure and acetic acid- induced writhing model were used to measure the analgesic activity of C. radicans. The hypoglycemic, anti-diarrheal and CNS antidepressant activities were determined by oral glucose tolerance test, castor oil-induced diarrheal model and thiopental-sodium induced sleeping time test in mice, respectively. Results All the organic soluble fractions of C. radicans contained phenolic compounds varying from 6.38 to 60.13 mg of GAE/gm of extractive, while in DPPH assay, EASF showed the highest free radical scavenging activity with IC50 is 4.69 μg/ml. The PESF exhibited highest thrombolytic activity (57.14% clot lysis) and the DMSF showed maximum 53.95% inhibition of heat-induced hemolysis of human RBCs. In both tail immersion and acetic acid induced writhing models, the PESF, DMSF, EASF at the doses of 200 and 400 mg/kg body weight, induced a significant (P < 0.001) decrease in the painful sensation in mice. Substantial (P < 0.05) anti-hyperglycemic activity of test samples was found in mice loaded with glucose at the same doses mentioned earlier. Castor oil induced diarrheal test of the plant extractives has shown significant effect in comparison to control group. In CNS antidepressant activity assay, the test samples were able to reduce the duration of sleep in mice caused by thiopental administration. Conclusion All these findings revealed that C. radicans possess significant antioxidant, thrombolytic, membrane stabilizing, analgesic, hypoglycemic, anti-diarrheal and CNS antidepressant activities.

This study investigated the synthesis, characterization and in vitro antioxidant activity of silver nanoparticles (AgNPs) using the aqueous leaf extract of Justicia carnea.  The aqueous leaf extract of J. carnea was used as a potential reducing and capping agent. To identify the compounds responsible for the reduction of silver ions, the functional groups present in the plant extract were subjected to FTIR. The in vitro antioxidant activity of synthesized nanoparticles was evaluated in terms of ferric reducing antioxidant potential (FRAP), DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2`-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) free radicals scavenging assays. The surface plasmon resonance confirmed the formation of AgNPs with maximum absorbance at kmax = 446 nm. FTIR revealed the biological macromolecules of J. carnea leaf extract involved in the synthesis and stabilization of AgNPs. UV-Visible spectrophotometer showed absorbance peak in the range of 436-446 nm. The silver nanoparticles exhibited moderate antioxidant activities compared to standard antioxidants (ascorbic acid and BHT). These results confirmed this protocol as simple, eco-friendly, nontoxic and an alternative for conventional physical and chemical methods. It can be concluded that J. carnea leaf extract can be used effectively in the production of potential antioxidant AgNPs which could be useful in various bio-applications such as cosmetics, food and biomedical industry.
