Abstract The aim of this work was to be combine two pharmocophoric nuclei viz, triazole and chalcone and evaluate their antitubercular activity. Propargylated vanillin was condensed with differently substituted acetophenones to produce various chalcones (3a-c). Propargyl chalcones were then made to react with benzyl azides (2a-d) using the technique of Click chemistry and this reaction yielded triazole-chalcone hybrids (4a-l) in good yields, ranged from 34 to 93%. These hybrids were evaluated for their antitubercular activity, from the results it was found that triazole and chalcone on combination exhibited enhanced bioactivity thereby supported the theory of synergistic effect. The conjugate 4a and 4f were found to be most potent with MIC of 1.6 µg/ml. Molecular docking studies of bioactive compounds were in good congruence with in-vitro studies.

Background: Rheumatoid Arthritis (RA) is an autoimmune disorder of symmetric synovial joints which is characterized by the chronic inflammation with 0.5-1% prevalence in developed countries. Presence of persistent inflammation is attributed to the major contribution of key inflammatory cytokine and tumour necrosis factor- alpha (TNF- &#945;). Recent drug designing studies are developing TNF-&#945; blockers to provide relief from the symptoms of the disease such as pain and inflammation. Available blockers are showing certain limitations such as it may enhance the rate of tuberculosis (TB) occurrence, lymphoma risk, cost issues and certain infections are major concern. Discussed limitations implicated a need of development of some alternative drugs which exhibit fewer side effects with low cost. Therefore, we have identified anti-inflammatory compounds in an underutilized fruit of Baccaurea sapida (B.sapida) in our previous studies. Among them quercetin have been identified as the most potent lead compound for drug designing studies of RA. </P><P> Methods: In the present article, characterization of quercetin has been carried out to check its drug likeliness and molecular docking study has been carried out between TNF- &#945; and quercetin by using AutoDock 4.2.1 software. Further, inhibitory effect of B. sapida fruit extract on RA plasma has been analysed through immunological assay ELISA. </P><P> Results: Our in-silico analysis indicated that quercetin showed non carcinogenic reaction in animal model and it may also cross the membrane barrier easily. We have studied the ten different binding poses and best binding pose of TNF-&#945; and quercetin showed -6.3 kcal/mol minimum binding energy and 23.94 &#181;M inhibitory constant. In addition to this, ELISA indicated 2.2 down regulated expression of TNF-&#945; in RA compared to control. </P><P> Conclusion: This study may further be utilized for the drug designing studies to reduce TNF-&#945; mediated inflammation in near future. This attempt may also enhance the utilization of this plant worldwide.

Severely ill coronavirus disease 2019 (COVID-19) patients show elevated concentrations of pro-inflammatory cytokines, a situation commonly known as a cytokine storm. The p38 MAPK receptor is considered a plausible therapeutic target because of its involvement in the platelet activation processes leading to inflammation. This study aimed to identify potential natural product-derived inhibitory molecules against the p38α MAPK receptor to mitigate the eliciting of pro-inflammatory cytokines using computational techniques. The 3D X-ray structure of the receptor with PDB ID 3ZS5 was energy minimized using GROMACS and used for molecular docking via AutoDock Vina. The molecular docking was validated with an acceptable area under the curve (AUC) of 0.704, which was computed from the receiver operating characteristic (ROC) curve. A compendium of 38,271 natural products originating from Africa and China together with eleven known p38 MAPK inhibitors were screened against the receptor. Four potential lead compounds ZINC1691180, ZINC5519433, ZINC4520996 and ZINC5733756 were identified. The compounds formed strong intermolecular bonds with critical residues Val38, Ala51, Lys53, Thr106, Leu108, Met109 and Phe169. Additionally, they exhibited appreciably low binding energies which were corroborated via molecular mechanics Poisson–Boltzmann surface area (MM-PBSA) calculations. The compounds were also predicted to have plausible pharmacological profiles with insignificant toxicity. The molecules were also predicted to be anti-inflammatory, kinase inhibitors, antiviral, platelet aggregation inhibitors, and immunosuppressive, with probable activity (Pa) greater than probable inactivity (Pi). ZINC5733756 is structurally similar to estradiol with a Tanimoto coefficient value of 0.73, which exhibits anti-inflammatory activity by targeting the activation of Nrf2. Similarly, ZINC1691180 has been reported to elicit anti-inflammatory activity in vitro. The compounds may serve as scaffolds for the design of potential biotherapeutic molecules against the cytokine storm associated with COVID-19.
