Abstract: The present disclosure describes novel protein kinase inhibitors and methods for preparing them. The pharmaceutical compositions comprising such protein kinase inhibitors and methods of using them for treating cancer and other diseases, conditions, or disorders, which respond to the inhibition of epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK) activity, or a combination thereof, are also described.

Abstract: Compounds are provided having the structure of the following Formula I: where R, R1, R2, R3a and R3b are as defined herein. Pharmaceutical compositions comprising such compounds, as well as methods related to their manufacture and use, are also provided.

Abstract: A method for preparing a transgenic animal of simultaneous multiple-gene expression is provided. Additionally, a method for preparing a transgenic embryo, which introduces both phytase gene and human myxovirus resistant gene A into a target embryo, to obtain a transgenic embryo is provided. The transgenic animal of simultaneous multiple-gene expression can be achieved by transplanting the transgenic embryo into the body of a female target animal. A significant advantage of the foregoing methods, among many others, exists in that the simultaneous expression of multiple genes can be achieved in one transgenosis, which provides a convenient method for the preparation of combined-gene transferred animals.

Abstract: Ansamycins and methods of preparing and using the same are described. At least some of these ansamycins exhibit one or more of improved aqueous formulation ability, chemical stability, and bioavailability. Some of the derivatives described are dimers. These and others described can include one or more solubilizing groups that have expected merit in rendering the overall compounds useful as drugs and prodrugs.

Abstract: Novel purine compounds and tautomers and pharmaceutically acceptable salts thereof are described, as are pharmaceutical compositions comprising the same, complexes comprising the same, e.g., HSP90 complexes, and methods of using the same.

Abstract: Novel purine compounds of Formula I. and tautomers, pharmaceutically acceptable salts, and prodrugs thereof, wherein X is S, S(O), or S(O)2; and O is selected from alkyl, cycloalkyl, arylalkyl, aryl, heteroaryl, and heterocyclic, all optionally substituted, are described, as are pharmaceutical compositions comprising the same, complexes comprising the same, e.g., HSP90 complexes, and methods of using the same.

Abstract: Novel purine compounds and tautomers and pharmaceutically acceptable salts thereof are described, as are pharmaceutical compositions comprising the same, complexes comprising the same, e.g., HSP90 complexes, and methods of using the same. Methods of using the novel purine compounds of the invention, and tautomers and pharmaceutically acceptable salts thereof, include their use in inhibiting heat shock protein 90's (HSP90's) to thereby treat or prevent HSP90-dependent diseases, e.g., proliferative disorders such as breast cancer.
