    6a-e: 7a-e: 8a-e: respectively. The newly synthesized compounds were characterized by using IR, NMR ( 1 H and 13 C), mass spectral studies, elemental analyses. All the synthesized compounds were studied for their docking interaction with target protein 6COX and screened for their in vivo analgesic mode of action against swiss albino mice (animal model) using acetic-acid induced writhing test. Consequently, docking simulations data justifies the potential of synthesized series as an analgesic and very well correlated with in vivo study.

    Abstract The 2019-nCoV (COVID-19; novel coronavirus disease-2019) outbreak is caused by the coronavirus, and its continued spread is responsible for increasing deaths, social and economic burden. COVID-19 created a chaotic situation worldwide and claimed the lives of over 5,027,183 and 248,467,363 confirmed cases have been reported so far as per the data published by WHO (World Health Organization) till 5 th November 2021. Scientific communities all over the world are toiling to find a suitable therapeutic drug for this deadly disease. Although till date no promising drug has been discovered for this COVID-19. However, as per the WHO, over 102 COVID-19 vaccines are in clinical development and 185 in pre-clinical development. Naturally occurring phytoconstituents possess considerable chemical richness in the form of anti-viral and anti-parasitic potential and have been extensively exploited for the same globally. Still, phytomedicine-based therapies are considered as the best available treatment option to minimize and treat the symptoms of COVID-19 because of the least possible side effects compared to synthetic drugs recommended by the physicians/clinicians. In this review, the use of plant chemicals as a possible therapeutic agent for severe acute respiratory syndrome coronavirus 2 (SARS CoV2) is highlighted with their proposed mechanism of action, which will prove fruitful and effective in finding a cure for this deadly disease.

    Abstract Traditional medicine is a blend of information gathered over generations from various communities and cultures. Pinus roxburghii Sargent (Pinaceae) commonly known as "chir pine" is widely used in traditional and folkloric systems of medicine. The all parts of the plant are believed to possess medicinal qualities in Ayurvedic and Unani systems of medicine. In these traditional systems of medicine, the plant is used to heal many diseases, including afflictions of the eyes, ears, throat, blood, and skin. The plant parts are rich in various bioactive compounds such as α-pinene, abietic acid, quercetin and xanthone. Resin acids and flavanoid form a major portion of these bioactive compounds. This review presents examples of traditional medicinal uses for P. roxburghii, and subsequently explores the current understanding of the chemical, pharmacological, and biochemical properties of the extracts and the main active constituents found in each tissue of the plant. Clinical trial information is also included where available. Careful evaluation of these data may be helpful for scientists and researchers to discover and evaluate the specific chemical entities responsible for the traditional medicinal uses of P. roxburghii.

    Abstract The present study attempts to establish a relationship between ethnopharmacological claims and bioactive constituents present in Pinus roxburghii against all possible targets for diabetes through molecular docking and to develop a pharmacophore model for the active target. The process of molecular docking involves study of different bonding modes of one ligand with active cavities of target receptors protein tyrosine phosphatase 1-beta (PTP-1β), dipeptidyl peptidase-IV (DPP-IV), aldose reductase (AR), and insulin receptor (IR) with help of docking software Molegro virtual docker (MVD). From the results of docking score values on different receptors for antidiabetic activity, it is observed that constituents, namely, secoisoresinol, pinoresinol, and cedeodarin, showed the best docking results on almost all the receptors, while the most significant results were observed on AR. Then, LigandScout was applied to develop a pharmacophore model for active target. LigandScout revealed that 2 hydrogen bond donors pointing towards Tyr 48 and His 110 are a major requirement of the pharmacophore generated. In our molecular docking studies, the active constituent, secoisoresinol, has also shown hydrogen bonding with His 110 residue which is a part of the pharmacophore. The docking results have given better insights into the development of better aldose reductase inhibitor so as to treat diabetes related secondary complications.

    Abstract Synthesis of fourteen analogues of bacillamide, a bioactive tryptamide alkaloid of marine origin, has been accomplished through a highly efficient convergent route. The present solvent-free protocol involves the formation of thiazole ring in the initial step followed by amide coupling between substituted ethyl 2-alkyl/aryl/heteroaryl/amino/aminoarylthiazole-4-carboxylates and tryptamine in presence of 2-hydroxy-4,6-dimethylpyrimidine, a solid phase catalyst to yield N-[2-(1H-indol-3-yl)ethyl]-2-alkyl/aryl/heteroaryl/amino/aminoarylthiazole-4-carboxamides as bacillamide analogues having structural variation at position-2 of thiazole ring. Bacillamide and its analogues were evaluated for their cytotoxic activity against three cancer cell lines (HCT-116, MDA-MD-231 and JURKAT cell lines) using colorimetric cell proliferation assay. Compounds 17a and 17b exhibited potent anti-cell proliferation activity with IC50 values in the range of ∼3.0 μM and ∼0.1-0.6 μM, respectively against these cell lines. Preliminary mechanism of action studies indicates that these compounds initiate caspase dependent apoptosis. Also, compounds 16d, 16f, 17a and 17d exhibited excellent anti-inflammatory activity comparable to well-known NSAID indomethacin and better to bacillamide, when evaluated using carrageenan induced rat hind paw oedema method.

    Abstract Current Letter presents design, synthesis and biological evaluation of a novel series of pyrazolylthiazole carboxylates 1a-1p and corresponding acid derivatives 2a-2p. All 32 novel compounds were tested for their in vivo anti-inflammatory activity by carrageenan-induced rat paw edema method as well as for in vitro antimicrobial activity. All the tested compounds exhibited excellent AI activity profile. Three compounds 1p (R=Cl, R(1)=Cl), 2c (R=H, R(1)=F) and 2n (R=Cl, R(1)=OCH3) were identified as potent anti-inflammatory agents exhibiting edema inhibition of 93.06-89.59% which is comparable to the reference drug indomethacin (91.32%) after 3h of carrageenan injection while most of the other compounds displayed inhibition ⩾80%. In addition, pyrazolylthiazole carboxylic acids (2a-2p) also showed good antimicrobial profile. Compound 2h (R=OCH3, R(1)=Cl) showed excellent antimicrobial activity (MIC 6.25μg/mL) against both Gram positive bacteria comparable with the reference drug ciprofloxacin (MIC 6.25μg/mL).

    Abstract A series of novel 2,5-diarylpyrazolo[1,5-a]pyrimidin-7-amines were designed as COX-2 inhibitors by molecular docking studies and their synthesis was accomplished via an expeditious one-pot reaction. Structures of the compounds were established by NMR ((1)H-(13)C), IR spectroscopy and high resolution mass spectrometry. All the eleven compounds have been screened for their in vivo anti-inflammatory activity on rats by carrageenan-induced rat paw edema assay. Correlation studies of calculated moldock score and observed percentage inhibition have also been carried out which concluded that the synthesized 2,5-diarylpyrazolo[1,5-a]pyrimidin-7-amines act as potent anti-inflammatory agents up to the 4th hour of study.
