Glucopyranose-nitrosourea compounds having lower alkyl group and/or 2-chloroethyl group as substituent(s), are produced at high yield by reacting amino-glucopyranose compounds having lower alkoxy group and/or amino group(s) (or an acid-added amino group) as substituent(s), with o-nitro- or o-cyano-phenyl N-substituted-N-nitrosocarbamate compounds having lower alkyl group or 2-chloroethyl group as substituent. 1-(Lower alkyl or 2-chloroethyl)-3-(D-glucopyranos-6-yl)-1-nitrosourea compounds included within the scope of the nitrosourea compounds are novel. The nitrosourea compounds produced by this invention all show antitumor activity, among which the novel compounds exhibit excellent physical and pharmacological properties.

Compounds that cause reversible night blindness may be used to treat ophthalmic conditions associated with the overproduction of waste products that accumulate during the course of the visual cycle. Provided are methods and compositions using such compounds and their derivatives to treat, for example, the macular degenerations and dystrophies or to alleviate symptoms associated with such ophthalmic conditions. Such compounds and their derivatives may be used as single agent therapy or in combination with other agents or therapies.
