A new class of 4′-demethyl-4-deoxypodophyllotoxin derivatives has been designed and synthesized as tubulin-HDAC dual inhibitors. Biological evaluation of these hybrids included the inhibitory activity of HDAC, in vitro cell cycle analysis in HCT-116 cells as well as cytotoxicity against two cancer cell lines (A549 and HCT116). The distance and angle between the HDAC capping group and the zinc binding group were systematically varied. Compounds 14a and 14c showed most potent dual inhibitory activity and powerful antiproliferative activity on HCT116 and A549 cell lines. This journal is

An exceptionally chemoselective method for the direct conversion of azides to N-(tert-butoxycarbonyl)-protected amines under catalytic transfer-hydrogenation conditions, using the Lindlar catalyst, is reported. The extremely labile functional groups such as N-Cbz, benzyl ester are shown to be inert under the reaction conditions. The present method allows us to synthesize orthogonally protected (N-Cbz and N-Boc) 1,2-diamino systems, which will be immensely useful in organic synthesis.

Novel N-substituted mercaptopropanamide derivatives of the formula: STR1 wherein R1 is mercapto or a group convertible into mercapto when cleaved within the biobody, W is hydrogen atom, an alkyl or an aralkyl, R2 is an aryl which may optionally have substituent(s), a heterocyclic group which may optionally have substituent(s), or an alkyl which may optionally have substituent(s), X is a cycloalkylene, a cycloalkylidene, or a phenylene which may optionally have substituent(s) or may optionally be fused with other ring, and R3 is carboxyl or a group convertible into carboxyl when cleaved within the biobody, or a pharmaceutically acceptable salt thereof, and a solid solution of said N-substituted mercaptopropanamide derivative with an amino acid, which have excellent enkephalinase inhibitory activity and are useful for the treatment of mild to moderate pain, and a pharmaceutical composition containing said compounds as an active ingredient, and processes for preparing these compounds.
