Abstract:
The present invention discloses a new process for the synthesis of tamsulosin and its aralkylamine derivatives, especially (R)-(−)-5-{2-[2-(2-alkoxyphenoxy) ethylamino]propyl}-2-alkoxybenzenesulfonamides having the following formula 1 (where R1 and R2 represent C1-C4 alkyl groups) and their hydrochloride thereof, and other various pharmaceutical used salts. Tamsulosin hydrochloride (R1=Et, R2=Me, in its hydrochloride salt form) is an antagonist of α-A adrenoceptors in the prostate. Tamsulosin•HCl occurs as white crystals, which melt with decomposition at approximately 230° C. It is sparingly soluble in water and in methanol, slightly soluble in glacial acetic acid and in ethanol, and practically insoluble in ether.

Abstract:
The present invention discloses a photo-induced DNA-cleaving agent composition comprises N-aryl-N-(alkyl or arylalkyl)hydroxylamine having the following formula: ##STR1## wherein R is C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, phenoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl)wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl); R.sub.2 is hydrogen; R.sub.3 is hydrogen or phenyl; R.sub.4 is hydrogen, phenyl, hydroxylphenyl, methoxyphenyl, dimethoxyphenyl, dimethylaminophenyl or naphthyl. The present N-aryl-N-(alkyl or arylalkyl)hydroxylamine is stable in dark, but it can react with O.sub.2 to form HO. radicals under irradiation of UV light for a period of 2-3 hours. The HO. radicals then react with DNA to accomplish cleavage of DNA.
