Synthesis and hypotensive activity of 4-(substituted pyridyl)-1,4-dihydropyridine derivatives was written by Ashimori, Atsuyuki;Ono, Taizo;Uchida, Takeshi;Ohtaki, Yutaka;Fukaya, Chikara;Watanabe, Masahiro;Yokoyama, Kazumasa. And the article was included in Chemical & Pharmaceutical Bulletin in 1990.SDS of cas: 116308-35-1 This article mentions the following:
A series of 4-(substituted pyridyl)-1,4-dihydropyridine derivatives I (R = H, halo, CF3, etc.) were synthesized and their hypotensive effects examined Several compounds have a hypotensive activity parallel to that of nicardipine; the 4-(3-trifluoromethyl-2-pyridyl) and 4-(2-trifluoromethyl-3-pyridyl) derivatives, in particular, had approx. twice the duration of nicardipine, and the 4-(4-cyano-2-pyridyl) derivative had the most potent hypotensive activity of all the derivatives synthesized. In the experiment, the researchers used many compounds, for example, 2-(Trifluoromethyl)nicotinaldehyde (cas: 116308-35-1SDS of cas: 116308-35-1).
2-(Trifluoromethyl)nicotinaldehyde (cas: 116308-35-1) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine derivatives are also useful as small-molecule 浼?helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.SDS of cas: 116308-35-1
