A series of novel 3-substituted quinoxalin-2-carboxamides were designed as per the pharmacophoric requirement for 5-HT(3) receptorantagonists and prepared by microwave irradiation and also by conventional method. The compounds were characterized by spectral data (IR, (1)H NMR, and MS) and the purity was ascertained by microanalysis. The synthesized compounds were evaluated for 5-HT(3) antagonisms

compounds that could reactivate OP-inhibited AChE. Recently, a number of non-oxime compounds was discovered in which the 4-amino-2-((diethylamino)methyl)phenol (ADOC) motif proved to be able to reactivate OP-inhibited AChE to some extent. In this paper several structural derivatives of ADOC were synthesized and screened for their ability to reactivate human AChE (hAChE) inhibited by the nerve agents

A series of 3-chloroquinoxaline-2-carboxamides were designed and prepared by the condensation of 3-chloro-2-quinoxaloylchloride with appropriate Mannich bases of the p-aminophenol in the microwave environment. The synthesized compounds were evaluated for serotonin3 (5-HT3) receptor antagonistic activities in longitudinal muscle-myenteric plexus (LMMP) preparation from guinea pig ileum against the 5-HT3 agonist, 2-methyl-5-HT. Compound 3g exhibited comparable 5-HT3 antagonistic activity (pA2 6.4) to that of standard antagonist Ondansetron (pA2 6.9), while the other compounds exhibited mild to moderate 5-HT3 antagonistic activities.
