Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

متن کامل1-Formyl-r-2,c-6-bis(4-methoxyphenyl)-t-3,t-5-dimethylpiperidin-4-one
In the title compound, C(22)H(25)NO(4), the piperidine ring adopts a distorted boat conformation. The methyl groups at the 3 and 5 positions of the piperidine ring are in axial and equatorial orientations, respectively. Both H and O atoms in the aldehyde group are disordered over two positions with occupancies of 0.534 (5) and 0.466 (5). In the crystal, the mol-ecules are linked into a three-di...

In the title compound, C(19)H(19)F(2)NO, the piperidinone ring adopts a chair conformation. The crystal packing is stabilized by C-H⋯O and C-H⋯F inter-molecular inter-actions, generating centrosymmetric dimers of R(2) (2)(14) and R(2) (2)(24) rings.
