摘要:
2,6-Dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid esters of the general formula: ##STR1## wherein R is a substituted alkyl or terpenyl. A method for preparing said esters comprises reacting esters of acetoacetic acid of the general formula: CH.sub.3 COCH.sub.2 COOR, wherein R is a substituted alkyl or terpenyl, with hexamethylenetetramine in the presence of ammonium acetate in ethanol at its boiling temperature; said esters of acetoacetic acid of the above general formula, hexamethylenetetramine and ammonium acetate can be used in stoichiometric proportions.
摘要:
New compounds of the nitrofuran series are provided, having the following general base formula: ##STR1## where R=CH.sub.2 CH.sub.2 CH.sub.2 OH; --CH(CH.sub.3)(CH.sub.2).sub.3 N(C.sub.2 H.sub.5).sub.2n=1,2and which may be in the form of salts.These compounds, both in the form of base and salt, exhibit a contact-action antiblastic effect. The advantage of these compounds resides in high selectivity of their action on tumoral cells combined with a germicidal activity.These compounds may be used in the medicine as an active source of antiblastic preparations.
摘要:
1-(5-Fluoruacil-1)-2,5-di-O-acetyl-.beta.-D-glucofuranurono-6,3-lactone has the formula ##STR1## Said substance has a marked antiblastic action. The substance is less toxic compared with the known preparation of similar action.
