A series of pyrimidine and thiazine derivatives was synthesized by one-pot reaction of cyclopentanone with a mixture of an aromatic aldehyde, namely o-anisaldehyde, and different ureas, namely urea, guanidine and thiourea, respectively. Furthermore, cycloaddition reaction of active methylene reagents, namely acetyl acetone, malononitrile, ethyl cyanoacetate, cyanoacetamide and N-phenyl cyanoacetamide with 2,6-bis(2-methoxybenzylidene)cyclohexanone afforded chromene and quinoline derivatives in basic medium. The antitumor evaluation of some new compounds against three human cell lines, namely MCF-7, NCI-H460 and SF-268 showed significant and moderate activity compared with the positive control doxorubicin.

ABSTRACT. In the present study, we have synthesized novel Isopropyl 2-(4-substitutedbenzylidene)-5-methyl-3-oxo-7-phenyl-3,7-dihydro-2H-thiazolo[3,2-a]-pyrimidine-6-carboxylate derivatives (6a-j). Elemental analysis, IR, 1 H NMR and mass spectral data elucidated structure of newly synthesized compounds. The newly synthesized compounds were screened for antiinflammatory and anti microbial studies. Their biological activity data of the 10 compounds indicates that two compounds posses potent anti-inflammatory and five have antimicrobial activities.

“…They have a similar pharmacological profile to that of classical dihydropyridine based calcium channel modulators [8][9][10]. Nevertheless, DHPMs have attracted our attention because of the fact that several DHPMs have been examined for their antimicrobial properties in the recent years [11][12][13]. Structurally, all these derivatives differed with respect to the substituents on the two key positions i.e.…”

All these compounds were prepared via a multi-component reaction (MCR) involving sequential I 2 -mediated Biginelli reaction followed by Cu-free Sonogashira coupling. Some of them showed promising inhibitory activities when tested at 30 µM. One compound showed dose dependent inhibition of CM with IC 50 value of 14.76 ± 0.54 µM indicating o-alkynylphenyl substituted DHPM as a new scaffold for the discovery of promising inhibitors of CM.
