FIELD: organic chemistry, chemical technology, medicine, pharmacy.
SUBSTANCE: invention relates to novel substituted derivatives of noscapine of the general formula (1) 
or its racemates, optical isomers, or their pharmaceutically acceptable salts and/or hydrates possessing anticarcinogenic activity, and to a pharmaceutical composition as tablets, capsules or injection formulations placed into pharmaceutically acceptable package, ant to methods for their synthesis, and to a method for inhibition of proliferation by their using. In compounds of the formula (1) R1 represents a substitute of amino-group chosen from alkyl; R2 represents a substitute of cyclic system chosen from possibly substituted alkyl wherein substitutes are chosen from possibly substituted amino-group or azaheterocycle comprising possibly oxygen (O), sulfur (S) or nitrogen (N) atoms as an additional heteroatom, and added to alkyl group by nitrogen atom, possibly substituted aryl possibly substituted and possibly condensed heteroaryl comprising at least one heteroatom chosen from nitrogen, sulfur and oxygen atoms, possibly substituted sulfamoyl. Except for, invention relates to 3-(9-iodo-4-methoxy-6-methyl-5,6,7,8-tetrahydro-[1,3]-dioxolo-[4,5-g]-isoquinoline-5-yl)-6,7-dimethoxy-3H-isobenzofuran-1-one, 3-(9-chloromethyl-4-methoxy-6-methyl-5,6,7,8-tetrahydro-[1,3]-dioxolo-[4,5-g]-isoquinoline-5-yl)-6,7-dimethoxy-3H-isobenzofuran-1-one, 5-(4,5-dimethoxy-3-oxo-1,3-dihydroisobenzofuran-1-yl)-4-methoxy-6-methyl-5,6,7,8-tetrahydro-[1,3]-dioxolo-[4,5-g]-isoquinoline-9-carbaldehyde (or -9-carbonitrile, or -9-sulfonyl chloride, or -9-carboxylic acid) and 3-(9-methoxymethyl-4-methoxy-6-methyl-5,6,7,8-tetrahydro-[1,3]-dioxolo-[4,5-g]-isoquinoline-5-yl)-6,7-dimethoxy-3H-isobenzofuran-1-one, and method for their synthesis. Also, invention relates to combinatory and focused libraries.
EFFECT: improved method of synthesis, valuable medicinal properties of compounds and pharmaceutical composition.
