A novel glucopyranose derivative of general formula:
[wherein, R represents a hydrogen atom, a hydroxy group or an alkoxy group of from 1 to 4 carbon atom(s),
R' represents a single bond or an oxycarbonylalkyl group of from 2 to 20 carbon atoms,
R2 and R6, independently, represent a hydrogen atom or a general formula:
(wherein, R10 represents a hydrogen atom, an alkyl or alkoxy group of from 1 to 7 carbon atom(s) or a halogen atom, and m represents 1, 2 or 3.), respectively,
R3 represents an alkylene group of from 1 to 20 carbon atom(s),
R4 represents a hydrogen atom or a general formula:
(wherein, R" represents a hydrogen atom, an alkyl or alkoxy group of from 1 to 7 carbon atom(s) or a halogen atom, and n represents 1, 2 or 3.),
R5 represents an oxycarbonyl group of from 2 to 20 carbon atoms,
R7 represents a hydrogen atom or a hydroxy group.
With the proviso that, R2, R4 and R6 do not represent hydrogen atoms at the same time.]
or non-toxic salts thereof possess enhancing activity of cellular immunity (e.g. mitogenic activity) to living tissue as shown in the experiment hereinbefore, and therefore be useful for enhancing agent of immunity and, possess and inducing activity of TNF, an inducing activity of IL-1 and an inducing activity of IFN, and therefore be useful for anti-tumor agent.
