摘要:
Novel polythiophene compounds useful as anti-tumor agents are described. Preferred compounds of formula (I) wherein n is 0-2 and R2 and R3 are optionally substituted 2-thienyl or 3-thienyl have been found to exhibit selective cytotoxic activity against transformed human cells. Pharmaceutical compositions containing the described polythiophene compounds are expected to exhibit good chemotherapeutic activity against slow growing tumors based on tumor cell line assays. A method for treating patients having tumors utilizing the disclosed polythiophene compounds is also described.

摘要:
Process for the preparation of 2-methoxyimino-2-arylacetic esters of formula (I) in which R is C1-C12alkyl, which comprises reacting an appropriately substituted boronic acid of general formula (II) or the trimeric form (III) herein, which is in equilibrium with it, in the presence of a Pd catalyst, with a methoxyiminoacetic ester of formula (IV) in which R is C1-C12alkyl and X is a leaving group. According to a further process variant, in principle the groups which split off the two reactants may change places. The process can be applied not only to phenyl derivatives but also to larger ring systems (naphthyl, pyridyl, heterocycles).
摘要:
The invention concerns compounds of formula (I ou II), or their salts, in which the radicals have for instance the following meaning: R1 and R2 are each hydrogen, C1-C8 alkyl, cyano or -NO2 or together are (-CF2-)m, -CF(OCH3)-CF2-CF(OCH3)-, -CF[NH2]-CF2-CF[-NH2]-, -C(=O)-O-C(=O)-, -C(=NH)-NH-C(=NH)- or -C(=O)-NH-C(=O)-; R3 and R4 are methyl; A1 and A2, independently of each other, are formyl, an acetal or thioacetal radical, phenyl, pyridiniumyl, pyridyl or other heterocyclic groups, or groups of formula (III or IV); X1 and X2 are S, O or N(R18); Y1 and Y2 are =CH- or =N-; R5 and R6 are hydrogen, halogen, -B(OH)2, C1-C8 alkyl, C1-C8 alkylthio, cyano, nitro, -N(R17)2, -C(=O)-R19, -C≡CH, phenyl or pyridyl, and R9 is a bridging group containing up to three hetero-atoms.
