In this study, a group of 4-substituted benzoyltaurinamide derivatives were designed, synthesized, and investigated for their anticancer activity against three cancer cell lines and one nontumorigenic cell line by MTT assay. Among the final compounds, methoxyphenyl derivatives 14, 15, 16 were found to be effective against all the tested cancerous cell lines with promising selectivity. The most active compounds were further evaluated to determine the molecular mechanism of their anticancer activity by using western blot assay and the Annexin V-FITC/PI test. Compound 14 (in SH-SY5Y and MDA-MB-231 cell lines) and 15 (in SH-SY5Y cell line) were found to induce intrinsic apoptotic pathway by upregulating BAX, caspase-3, and caspase-9, while downregulating Bcl-2 and Bcl-xL expression levels. According to mechanistic studies, compounds displayed their anticancer activity via three different mechanisms: a. caspase-dependent, b. caspase-independent, and c. caspase-dependent pathway that excluded caspase-9 activation. As a result, this study provides interesting data which can be used to design new taurine-based anticancer derivatives.

Hit optimization of the class of quinazoline containing histamine H 4 receptor (H4R) ligands resulted in a sulfonamide substituted analogue with high affinity for the H4R. This moiety leads to improved physicochemical properties and is believed to probe a distinct H4R binding pocket that was previously identified using pharmacophore modeling. By introducing a variety of sulfonamide substituents, the H4R affinity was optimized. The interaction of the new ligands, in combination with a set of previously published quinazoline compounds, was described by a QSAR equation. Pharmacological studies revealed that the sulfonamide analogues have excellent H4R affinity and behave as inverse agonists at the human H4R. In vivo evaluation of the potent 2-(6-chloro-2-(4-methylpiperazin-1-yl)quinazoline4-amino)-N- phenylethanesulfonamide (54) (pki = 8.31 ± 0.10) revealed it to have anti-inflammatory activity in an animal model of acute inflammation.

In this study, inspired by the structures of the taltrimide, 2-phthalimidoethanesulphonamide, and the anilide pharmacophore known to be synthetically produced anticonvulsant compounds, fifteen N-phenyl-2- phtalimidoethanesulfonamide derivatives bearing substituents with diverse electronic and hydrophobic features on N-phenyl ring were synthesized. The structural confirmation of the title compounds was achieved by interpretation of spectral and analytical data. The anticonvulsant activity of the title compounds was determined against maximal electroshock seizure in mice at a dose level of 100 mg/kg. The preliminary screening results indicated that the exchange of the N-isopropyl moiety for an N-phenyl ring in the taltrimide molecule abolished the anticonvulsant activity. However, introducing certain substituents, such as nitro, methyl, and chloro, into the N-phenyl ring lead to more active compounds in comparison to the unsubstituted derivatives.
