A series of chalcone derivatives (1a–2i) were designed based on isoliquiritigenin (the most active natural chalcone non-competitive neuraminidase (NA) inhibitor). Molecular modeling studies revealed that isoliquiritigenin and its designed analogs occupied 430-loop cavity of NA and interacted favorably with catalytic site residues. The favorable derivatives were synthesized and evaluated for cytotoxicity

and N–H⋯N ones observed in the known structure. DFTcalculations reveal that the three conformers of the known polymorph deviate from the minimum energy conformation which is adopted in our crystal form to compensate for the absence of strong intermolecular contacts. Second, conformerism is reported for (E)-1-(3-hydroxyphenyl)-3-(4-nitrophenyl)prop-2-en-1-one (2). Three crystallographically independent
Solid-phase synthesis of a parallel library of 3'-hydroxy-2,3-dihydrobenzothiazepines has been carried out through [4+3] annulation of alpha,beta-unsaturated ketones with aminothiophenol, using Wang resin as solid support. The synthesized compounds were evaluated for their potential as antibacterial, tumor inhibitors as well as acetyl- and butyrylcholinesterase inhibitors. None of the compounds showed any significant antibacterial activity. However, quite a few compounds showed significant potential as crown gall tumor inhibitors. These results reflect a strong exploratory potential in search of new benzothiazepines as source of anticancer agents. The results of the inhibition of cholinesterase revealed that benzothiazepines have a greater potential as butyrylcholinesterase inhibitors as compared to acetylcholinesterase. Moreover, the substitution of hydroxy group at C-3 in ring A led to increased activity when compared to unsubstituted- and 2'-OH substituted benzothiazepines. (C) 2008 Elsevier Ltd.

(AChE) and butyrylcholinesterase (BChE). Methods: The synthesis was carried out using Claissen-Schimdt condensation and the in vitro assay was conducted using Ellman Method. Results: Compounds 2b and 4b demonstrated as the best IC50 of 9.3 μM and 68.7 μM respectively, towards AChE and BChE inhibition. Moleculardockingstudies predicted that this activity might be due to the interaction of the chalcones
