Two diastereoisomers of the title compound, C(25)H(26)N(2)O, have been prepared by cyclo-addition between 1,3,3-trimethyl-2-methyl-eneindoline and C-phenyl-N-phenyl-nitrone. The stereochemistry of the major diastereoisomer, viz. S,R/R,S, is confirmed by the X-ray analysis. The oxazole and the pyrole rings have envelope conformations. The packing is stabilized by weak C-H⋯π inter-actions involvi...
Interest in central neurokinin (NK) 1 receptors has increased based on reports of the therapeutic potential for NK1 antagonists in anxiety and depression. In these studies, an ex vivo binding procedure was used to correlate NK1 receptor occupancy in striatum by NK1 antagonists with their potency to inhibit NK1 agonist-induced foot tapping in gerbils (GFT). The following compounds were administe...
The indole and phenyl ring systems in the title compound, C(18)H(18)N(2)S(2), are nearly coplanar, the indole and phenyl planes forming a dihedral angle of 6.5 (1)°. Supra-molecular aggregation is effected by N-H⋯S, C-H⋯S, N-H⋯π and C-H⋯π inter-actions. The crystal studied exhibited inversion twinning.
O-Cholesteryl-O-phenyl-N-phenylphosphoramidate (1) and four organotin (lV) derivatives of the ambidentate O-cholesteryl-O -phenyl phosphorothioate ligand formulated as Me(3) SnOSPR'R"(2), Ph(3)SnOSPR'R"(3), O(CH(2)CH(2)S)(2)Sn(n-Bu)OSPR'R"(4), S(CH(2)CH(2)S)(2)Sn(n-Bu)OSPR'R"(5), (R' = O-phenyl; R"= O-cholesteryl) were subjected to cytotoxicity screening against KB (nasopharingel carcinoma), OV...
Sponges are the simplest multicellular animals that lack defense mechanisms and rely on chemical defense that have been used by mankind to develop antimicrobial drugs against diseases. The present study was designed to demonstrate the antibacterial and antifungal activities of marine sponge Dysidea pallescens semipolar and nonpolar extracts. In this study, D. pallescens were collected from He...
