Serine- and threonine-derived diamine equivalents for site-specific incorporation of platinum centers in peptides, and the anticancer potential of these conjugates
stereoselective enzymatic desymmetrization of a series of prochiral 2-substituted-1,3-propanediamines have been carried out using Pseudomonas cepacia lipase as biocatalyst. Syntheses of novel opticallyactive orthogonally protected di- or triamines have been achieved for the first time with different grade of enantiodiscrimination depending on the C-2 substitution of the propane-1,3-diamine fragment

A series of vancomycin C-terminus guanidine modifications are disclosed that improve antimicrobial activity, enhance the durability of antimicrobial action against selection or induction of resistance, and provide two synergistic mechanisms of action independent of D-Ala-D-Ala binding that cause inhibition of cell wall biosynthesis, while inducing bacterial cell permeability. A contemplated compound contains two combined peripheral modifications, a (4-chlorobiphenyl)methyl (CBP) and C-terminus guanidine modification, that provide new treatments against not only vancomycin-sensitive, but especially vancomycin- resistant bacteria. The data demonstrate that the synergistic behavior of the peripheral modifications requires the presence of both the CBP and guanidine modifications in a single molecule versus their combined use as an equimolar mixture of singly modified compounds. A prototypical member of the series, G3- CBP-vancomycin (15), exhibits no hemolytic activity, displays no mammalian cell growth inhibition, and possesses improved and especially attractive in vivo pharmacokinetic (PK) properties.
The present invention provides a novel class of compounds that have the activity of inhibiting HSP90 enzyme and are useful as anti-cancer agents or such, and compounds that are useful as synthetic intermediates thereof. Specifically, the present invention provides compounds represented by the following formula (1), and pharmaceutically acceptable salts thereof:
