experimental part, p. 3870 - 3884 (2010/09/14)
A series of new cinnamido-pyrrolo[2,1-c][1,4]benzodiazepine conjugates (4a-d and 5a-d) and their dimers (6a-d) have been designed, synthesized and evaluated for their biological activity. The anticancer screening of compound 4a by the NCI exhibited signif
Selective reduction of secondary amides to amines in the presence of tertiary amides
Lee, Byung H.,Clothier, Michael F.
, p. 643 - 644 (2007/10/03)
Secondary amides activated with a Cbz group can be reduced to their corresponding hemiaminals using lithium borohydride. Hydrogenation then removes the Cbz and hydroxyl groups to produce the related amine. Tertiary amides are not affected.

, p. 4118 - 4134 (2007/10/02)
A series of (pyridylcyanomethyl)piperazines was prepared and evaluated for PAF-antagonist activity. Compounds were tested in vitro in a PAF-induced platelet aggregation assay and in vivo in a PAF-induced hypotension test in normotensive rats. Oral activity was ascertained through a PAF-induced mortality test in mice. The main structure-activity trends of the series were established. Activity was mainly found in four skeletons: 1-acyl-4-(3- pyridylcyanomethyl)-piperazine, 1-acyl-4-(4-pyridylcyanomethyl)piperazine, 1- acyl-4-(3-pyridylcyanomethyl)piperidine, and 1-acyl-4-cyano-4-(3- pyridylamino)piperidine. The acyl substituents, diphenylacetyl and 3,3- diphenylpropionyl, provided the most active compounds, and the introduction of an amine or hydroxy group in the 3,3-diphenylpropionyl substituent led to further improvement in oral activity. As a result, three of the most active compounds (100, 114, and 115) have been selected for further pharmacological development.
Synthesis and CNS-depressant profile of 3,4,5-trimethoxybenzoyl analogues
Kar
, p. 313 - 315 (2007/10/02)
A series of 3,4,5-trimethoxybenzoyl analogues with varying electronic and stereochemical characteristics has been synthesized. Many of these compounds (4, 5, 9, 12, 15) showed appreciable potentiation of pentobarbitone-induced hypnosis. Several analogues (1, 5, 6, 11, 12, 15) exhibited marked reduction of spontaneous motor activity (SMA).
