A polymer stabilizer comprising the following alkoxy compound:
the alkoxy compound: a compound obtained by alkoxylating at least one hydroxyl group contained in a compound of the following formula (1) containing one formyl group or carbonyl group and (n−

(wherein, n represents an integer of 3 or more).
The synthesis of a series of alkyl (having from C6 to C20 aglycones), cyclohexyl, and cyclohexylalkyl alpha-d-mannopyranosides, 6-deoxygenated analogs, thioglycosides, and sulfones derived thereof, is reported. Here, under the in vitro assay conditions used, none of the 15 tested compounds acted as an inhibitor of the mannose transfer catalyzed by the enzymes present in mycobacterial membrane and cell
