3-Benzhydryl-1,3,4-thiadiazole-2(3H)-thione
In the title compound, C15H12N2S2, the two phenyl rings and the planar (r.m.s. deviation = 0.002 Å) thia-diazole ring adopt a propeller conformation about the central C-H axis with H-C-C-C(phen-yl) torsion angles of 44 and 42° and an H-C-N-C(thia-diazole) torsion angle of 28°. Intra-molecular C-H⋯S and C-H⋯N contacts are observed. In the crystal, centrosymmetrically related mol-ecules associate...
متن کامل1-Benzhydryl-3-phenylurea and 1-benzhydryl-3-phenylthiourea derivatives: new templates among the CB1 cannabinoid receptor inverse agonists.
New 1-benzhydryl-3-phenylurea derivatives and their 1-benzhydryl-3-phenylthiourea isosteres were synthesized and evaluated for their human CB1 and CB2 cannabinoid receptor affinity. These compounds proved to be selective CB1 cannabinoid receptor ligands, acting as inverse agonists in a [35S]-GTPgammaS assay. The affinity of 3,5,5'-triphenylimidazolidine-2,4-dione and 3,5,5'-triphenyl-2-thioxoim...
متن کامل1-Methyl-3-phenylimidazolidine-2-thione
The asymmetric unit of the title cyclic thio-urea derivative, C10H12N2S, comprises two mol-ecules, each of which has a twist about the CH2-CH2 bond within the five-membered ring. The major difference between the independent mol-ecules is manifested in the relative orientations of the five- and six-membered rings [dihedral angles between the least-squares planes = 28.03 (11) and 41.54 (11)°]. A ...

The title compound, C(13)H(14)OS, crystallizes with two independent mol-ecules in the asymmetric unit. The unit cell contains three voids of 197 Å(3), but the residual electron density (highest peak = 0.24 e Å(-3) and deepest hole = -0.18 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupies this void. The crystal structure is stabilized by π-π inter-actions between the ...
