Mycobacterium kansasii, glycolipids

Present in the tetrasaccharide group of Mycobacterium kansasii glycolipid. 

The derivatives 3-<9-methyl-D-olivose (D-oleandrose, 3-<9-methyl-2,6-dideoxy-D-arabino-hexose), and 3-0-methyl-D-oliose (3-<9-methyl-2,6-dideoxy-D-/yvo-hexose) are components of steroidal glycosides obtained from Cynanchum othophyllum Schneid, a traditional Chinese medicine.148 A derivative 4-O-me-thyl-D-olivose has been identified as the terminal sugar of the tetrasaccharide moiety in the phenolic glycolipid of Mycobacterium kansasii.149...

Another synthesis of methyl 2,6-dideoxy 4-Q-methyl-a-D-arabino-hexopvranoside (17) fc.f.. ref. 17), this time from di-Q-acetyl-6-deoxy-D-glucal (45) (Scheme 9), confirmed the identity of the sugar at the non-reducing terminus of the tetrasaccharide moiety in the major phenol glycolipid of Mycobacterium kansasii.
