Abstract: The invention relates to isolated complexes comprising one or more galectin associated with Mgat5 modified glycan or polylactosamine modified glycan, and isolated lectin-Mgt5 modified glycan lattice comprising an array of multivalent interactions among lectins, Mgat5 modified glycans, polylactosamine modified glycans, and/or glycoproteins. Methods for evaluating a test compound for its ability to regulate receptor clustering through glycans on cell surfaces; and methods for regulating receptor clustering on cell surfaces comprising altering glycans on the cell surface associated with receptor clustering are also discovered.

Abstract: The invention relates generally to compositions comprising malonate compounds, and methods and uses of the compositions in the treatment of proliferative diseases. In particular the invention relates to a pharmaceutical composition comprising a compound of the formula I wherein * is ?C or ?O, R1 and R2 independently represent substituted or unsubstituted alkyl, alkenyl, alkynyl, alkylene, alkenylene, alkoxy, alkenyloxy, cycloalkyl, cycloalkenyl, aryl, aryloxy, arylalkoxy, aroyl, heteroaryl, heterocyclic, acyl, acyloxy, sulfonyl, sulfinyl, sulfenyl, amino, imino, azido, thiol, thioalkyl, thioalkoxy, thioaryl, nitro, ureido, cyano, halo, silyl, silyloxy, silythio, carboxyl, carbonyl, carbamoyl, carboxamide, carboxylic ester, phosphono, a substituted or unsubstituted aryl group fused to a cycloalkyl group, or a pharmaceutically acceptable salt thereof, and pharmaceutically acceptable carriers, excipients, and vehicles.

Abstract: The present invention relates to binding pockets of a polo domain. In particular, the invention relates to a crystal comprising a binding pocket of a polo domain. The crystal may be useful for modeling and/or synthesizing mimetics of a binding pocket or ligands that associate with the binding pocket. Such mimetics or ligands may be capable of acting as modulators of polo family kinases, and they may be useful for treating, inhibiting, or preventing diseases modulated by such kinases.

Abstract: The invention relates to isolated complexes comprising one or more galectin associated with a Mgat5 modified glycan or polylactosamine modified glycan, and isolated lectin-Mgt5 modified glycan lattice comprising an array of mulitvalent interactions among lectins, Mgat5 modified glycans, polylactosamine modified glycans, and/or glycoproteins. Methods for evaluating a test compound for its ability to regulate receptor clustering through glycans on cell surfaces; and methods for regulating receptor clustering on cell surfaces comprising altering glycans on the cell surface associated with receptor clustering are also disclosed.
