  • Patent number: 8962637
    Abstract: The present invention relates to substituted aromatic bicyclic compounds containing pyrimidine and pyridine rings of formula (I) having the structure as well as pharmaceutically acceptable salts thereof. The compounds of the present invention are useful as tyrosine kinase inhibitors, preferably SRC family kinases (SFKs) inhibitors, in particular as multi SFK/JAK. kinases inhibitors and even preferably as dual c-SRC/JAK kinases inhibitors, thereby inhibiting the STAT3 activation and therefore abnormal growth of particular cell types. Notably, the compounds of the present invention are useful for the treatment or inhibition of certain diseases that are the result of deregulation of STAT3.
    Type: Grant

  • Patent number: 7067653
    Abstract: The invention describes the synthesis of a panel of novel carbon-carbon linked carboranyl-containing 5,10,15,20-tetraphenylporphyrins bearing 25–44% boron by weight. In certain embodiments, a phenyl porphyrin compound has a carboranyl group attached to the phenyl group by a carbon-carbon linkage, wherein the phenyl group corresponds to the following formula where R7 through R11 are hydrogen, a carboranyl group, or are selected from the group consisting of hydroxyl, NMe3+, PMePh2+, PO(OH)2, SO3H, COOH, and NH2. In this embodiment, the carboranyl group is attached to the phenyl group by a carbon-carbon linkage, either one or two of R7 through R11 are other than hydrogen; and the phenyl porphyrin compound contains at least one phenyl group having at least one of said carboranyl groups.
