摘要:
The present invention provides compounds of the general formula: ##STR1## wherein R.sub.1 is a hydroxyl group or a methoxy radical, R.sub.2 is a hydrogen atom or a hyroxyl group and R.sub.3 is a hydrogen atom or a hydroxyl group, with the proviso that R.sub.2 and R.sub.3 are not simultaneously hydrogen atoms when R.sub.1 is a methoxy radical; and the pharmacologically acceptable salts thereof.The present invention also provides processes for the preparation of these compounds and pharmaceutical compositions containing them.
摘要:
This disclosure describes two technical procedures for the high-yield synthesis of heterocyclic seven-membered ring-systems by Dieckmann-condensation avoiding usual dilution techniques and long reaction times. Thus, it significantly increases the overall yields of the pharmaceutically active ingredients azelastine and flezelastine, whose synthesis, starting from these seven-membered heterocyclic rings, is reported elsewhere. Yields range from 80-89%, avoiding waste and increasing economics of the synthesis.

摘要:
The present invention is directed in part towards methods of modulating the function of serine/threonine protein kinases with quinazoline-based compounds. The methods incorporate cells that express a serine/threonine protein kinase, such as RAF. In addition, the invention describes methods of preventing and treating serine/threonine protein kinase-related abnormal conditions in organisms with a compound identified by the invention. Furthermore, the invention pertains to quinazoline compounds and pharmaceutical compositions comprising these compounds.
