Inflammation is a reaction of a living vascularised tissue to an injury. Conventional or synthetic drugs used in the treatment of inflammatory diseases are inadequate, it sometimes have serious side effects. So, number of herbal medicines is recommended for the treatment of inflammation that has no side effects. Hence our study focused to investigate the physicochemical, qualitative phytochemical analysis of bioactive compounds and In-vitro and In-vivo anti-inflammatory activity of Plumeria indica Linn (P. Indica) flowers extract which has boundless medicinal properties. The physicochemical evaluations carried out in terms of loss on drying, ash value, extractive values and acid insoluble ash value ect. Qualitative analysis of various phytochemical constituents was determined by the well-known test protocol available in the literature. The aqueous and ethanolic extract of P. Indica flowers was screened for in-vivo anti-inflammatory activity by carrageenan induced paw edema in rat model and in-vitro anti-inflammatory activity by human red blood cell membrane stabilization method. Phytochemical analysis revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids ect. Ethanolic extract showed best in vitro anti-inflammatory activity was screened for in vivo anti-inflammatory activity at the dose level of 250 and 500mg/kg. Indomethacin at the dose level of 10 mg/kg was used as reference standard drug. Both the extracts showed a dose dependent anti-inflammatory potential which provide scientific basis for the traditional claims of P. Indica flowers as an anti-inflammatory drug.

Species ofPicramniagenus are used in folk medicine to treat or prevent skin disorders, but only few species have been studied for biological activity and chemical composition.P. gracilisTul. is a native species from Central and South America and although its fruits are edible, phytochemical analysis or medicinal uses of this species are not known. In the search of candidates to antileishmanial drugs, this work aimed to evaluate the antileishmanial activity ofP. gracilisTul. inin vitroandin vivostudies. Only ethanolic extract of fruits showed leishmanicidal activity. The majoritarian metabolite was5,3′-hydroxy-7,4′-dimethoxyflavanoneether that exhibited high activity againstL. (V.) panamensis(EC5017.0 + 2.8 mg/mL, 53.7 μM) and low toxicity on mammalian U-937 cells, with an index of selectivity >11.8.In vivostudies showed that the flavanone administered in solution (2 mg/kg/day) or cream (2%) induces clinical improvement and no toxicity in hamsters with CL. In conclusion, this is the first report about isolation of5,3′-hydroxy-7,4′-dimethoxyflavanoneofP. gracilisTul. The leishmanicidal activity attributed to this flavanone is also reported for the first time. Finally, thein vitroandin vivoleishmanicidal activity reported here for5,3′-hydroxy-7,4′-dimethoxyflavanoneoffers a greater prospect towards antileishmanial drug discovery and development.

Iron oxide nanoparticles (IONPs) possess versatile utility in cancer theranostics, thus, they have drawn enormous interest in the cancer research field. Herein, we prepared polyethylene glycol (PEG)-conjugated and starch-coated IONPs (“PEG–starch–IONPs”), and assessed their applicability for photothermal treatment (PTT) of cancer. The prepared PEG–starch–IONPs were investigated for their physical properties by transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and dynamic light scattering (DLS). The pharmacokinetic study results showed a significant extension in the plasma half-life by PEGylation, which led to a markedly increased (5.7-fold) tumor accumulation. When PEG–starch–IONPs were evaluated for their photothermal activity, notably, they displayed marked and reproducible heating effects selectively on the tumor site with laser irradiation. Lastly, efficacy studies demonstrated that PEG–starch–IONPs-based PTT may be a promising mode of cancer therapy.

Some plants have been reported to be of medicinal values and reserve some antimicrobial properties. One of such plants is Mitracarpus scaber and its effect on bacterial growth is evaluated. The study aimed at evaluating the phytochemical analyses and antimicrobial potentials of Mitracarpus scaber against aquatic bacteria including Aeromonas, Bacillus, Vibrio and Staphylococcus Spp. Leaves of Mitracarpus scaber were collected, washed and air dried and phytochemical analysis and antimicrobial investigation of ethanolic and aqueous extracts of the leaves were carried out against a panel of bacteria isolated from diseased catfish from various farms. The phytoconstituents detected include saponins, tannins, flavonoids, tarpenoids, steroids, anthraquinones and alkaloids in both aqueous and ethanolic extracts. Both aqueous and ethanolic extracts of M. scaber showed varying degree of antibacterial activities but ethanolic extract showed a higher activity against the pathogens tested. The ethanolic extract had zones of inhibition similar to that of standard antibiotics (enrofloxacin) across all tested microbes.  The lowest minimum inhibitory concentration of ethanolic extract of M. scaber was against Bacillus sp with 10mg/ml while the highest was 85mg/ml against Staphylococcus species. The results of the assays showed promising evidences that M. scaber is a potential antibacterial agent against aquatic microbes.  However, further studies are recommended to fractionate its constituents and determine the in vitro and in vivo anti-microbial activities and the exact mechanism of action of the constituents.

In December 2019, a new severe acute respiratory syndrome coronavirus (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), emerged in Wuhan, China. Despite containment measures, SARS-CoV-2 spread in Asia, Southern Europe, then in America and currently in Africa. Identifying effective antiviral drugs is urgently needed. An efficient approach to drug discovery is to evaluate whether existing approved drugs can be efficient against SARS-CoV-2. Doxycycline, which is a second-generation tetracycline with broad-spectrum antimicrobial, antimalarial and anti-inflammatory activities, showed in vitro activity on Vero E6 cells infected with a clinically isolated SARS-CoV-2 strain (IHUMI-3) with median effective concentration (EC50) of 4.5 ± 2.9 µM, compatible with oral uptake and intravenous administrations. Doxycycline interacted both on SARS-CoV-2 entry and in replication after virus entry. Besides its in vitro antiviral activity against SARS-CoV-2, doxycycline has anti-inflammatory effects by decreasing the expression of various pro-inflammatory cytokines and could prevent co-infections and superinfections due to broad-spectrum antimicrobial activity. Therefore, doxycycline could be a potential partner of COVID-19 therapies. However, these results must be taken with caution regarding the potential use in SARS-CoV-2-infected patients: it is difficult to translate in vitro study results to actual clinical treatment in patients. In vivo evaluation in animal experimental models is required to confirm the antiviral effects of doxycycline on SARS-CoV-2 and more trials of high-risk patients with moderate to severe COVID-19 infections must be initiated.

AbstractAmide and ester conjugates of aceclofenac with polyamidoamine (PAMAM-G0) dendrimer zero generation and dextran (40 kDa) polymeric carrier, respectively, are presented. The prepared conjugates were characterized by UV, TLC, HPLC, IR, and 1H NMR spectroscopy. The average degrees of substitution of amide and ester conjugates were determined and found to be (12.5 ± 0.24) % and (7.5 ± 0.25) %, respectively. The in vitro hydrolysis studies showed that dextran ester conjugate hydrolyzed faster in a phosphate buffer solution of pH 9.0 as compared to PAMAM dendrimer G0 amide conjugate, and followed the first order kinetics. No amount of the drug was regenerated at pH 1.2 in simulated gastric fluid. The dextran conjugate showed short half-life as compared to the PAMAM dendrimer conjugate. Anti-inflammatory and analgesic activities of the dendrimer conjugate were found to be similar to those of the standard drug. Results of chronic ulceroginic activity showed deep ulceration and high ulcer index for aceclofenac, whereas lower ulcer index was found for the PAMAM dendrimer and dextran (40 kDa) conjugates. Experimental data suggest that PAMAM dendrimer and dextran (40 kDa) can be used as carriers for the sustained delivery of aceclofenac along with a remarkable reduction in gastrointestinal toxicity.
