Abstract: The present invention is directed to aziridinyl epothilone compounds as further described herein, and/or pharmaceutically-acceptable salts and/or solvates thereof having the following Formula: wherein K is —O—, —S—, or —NR7—; A is —(CR8R9)—(CH2)m-Z- wherein Z is —(CHR10)—, —C(?O)—, —C(?O)—C(?O)—, —OC(?O)—, —N(R11)C(?O)—, —SO2—, or —N(R11)SO2—; B1 is hydroxyl or cyano and R1 is hydrogen or B1 and R1 are taken together to form a double bond; R2, R3, and R5 are, independently, hydrogen, alkyl, substituted alkyl, aryl or substituted aryl; or R2 and R3 may be taken together with the carbon to which they are attached to form an optionally substituted cycloalkyl; R4 is hydrogen, alkyl, alkenyl, substituted alkyl, substituted alkenyl, aryl, or substituted aryl; R6 is hydrogen, alkyl or substituted alkyl; R7, R8, R9, R10, R11 and R12 are independently hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, heterocycloalkyl, substituted heterocycloalkyl, heteroaryl, or sub

Abstract: The present invention describes polynucleotides that have been discovered to correlate to the relative intrinsic sensitivity or resistance of cells, e.g., breast cell lines, to treatment with compounds that interact with and modulate, e.g., inhibit, protein tyrosine kinases, such as, for example, members of the Src family of tyrosine kinases, e.g., Src, Fgr, Fyn, Yes, Blk, Hck, Lck and Lyn, as well as other protein tyrosine kinases, including, Bcr-abl, Jak, PDGFR, c-kit and Eph receptors. These polynucleotides have been shown, through a weighted voting cross validation program, to have utility in predicting the resistance and sensitivity of breast cell lines to the compounds. The expression level or phosphorylation status of some polynucleotides is regulated by treatment with a particular protein tyrosine kinase inhibitor compound, thus indicating that these polynucleotides are involved in the protein tyrosine kinase signal transduction pathway, e.g., Src tyrosine kinase.
