RESUMO
BACKGROUND: Pyrazole is a well-known nucleus in the pharmacy field with a wide range of other activities in addition to anti-inflammatory and analgesic, i.e., anticonvulsant, antiviral, and anticancer activities. There are well-known marketed drugs having pyrazole moiety as celecoxib, and lonazolac as COX-II inhibitors. AIMS: We aim to synthesize better anti-inflammatory than existing ones. Thiophene is also known for its analgesic and anti-inflammatory action. Thus, the fusion of both gives better anti-inflammatory agents. In the present studies, derivatives from two series of pyrazole were prepared by reacting substituted chalcone (3a-3f) derivatives prepared from 2-acetyl thiophene. They substituted aromatic aldehydes with phenyl hydrazine to form (5a-5f) and with 2, 4-dinitro phenyl hydrazine giving compounds (6a-6f) separately. METHODS: Purified and characterized pyrazoles have been analyzed for in-vivo analgesic and anti-inflammatory activities by using standard methods. Compounds 5e, 5f, and 6d were proved to be potent analgesics and series (5a-5f) was found to have anti-inflammatory action, which was further validated using docking and ADME studies. RESULTS: The ADME profile of synthesized compounds was found to be satisfactory. CONCLUSION: The synthesized compounds can serve as lead for further drug designing.

BACKGROUND: Alkaloids are important phytoconstituents obtained from various plant sources. The study's primary goal is to assess the anti-Alzheimer potential of alkaloids using a molecular docking study. Alzheimer's disease (AD) is considered a gradual decline in memory, reasoning, decision-making, orientation to one's physical surroundings, and language. METHOD AND MATERIAL: The main target i.e. acetylcholinesterase proteins was selected for the molecular docking study. RESULT: The structures of various alkaloids were drawn using Chem Draw Software, PDB was retrieved from the RCSB PDB database, and molecular docking study was performed on Molergo Virtual Docker. The potential alkaloids were identified with anti-Alzheimer potency. CONCLUSION: Reserpine, vinblastine, ergotamine, and tubocurarine were found to exhibit potential anti-Alzheimer potency.
