Oleandomycins

Oleandomycin. Oleandomycin (17, R = CH ) was the primary factor in culture broths of S. antihioticus (69,70). Its aglycone, oleandoHde...

After seeding the nutrient medium with the preformed inoculum previously described, the mixture was subjected to agitation and aeration under aseptic conditions for 72 hours at 27°C to 28°C for the first 24 hours, then at 25°C to 26°C for the next 48 hours during this period, the pH was in the range of 6.4 to 6.8. Aeration was accomplished by cultivation under submerged conditions at an air flow rate of one volume of air per volume of medium per minute. After termination of the process, the mycelium was removed by filtration and the filtered broth found to contain 450 7of oleandomycin per ml of solution.

Oleandomycin, its ester (triacetyloleandomycin) and spiran rdn have a similar range of activity as erythromycin but are less active. Resistance develops only slowly in chnical practice. However, cross-resistance may occur between all four members of this group.

The most impressive application of 2-thiopyridyl and 2-thiopyrimidinyl donors is in the area of antibiotics. Thus, Woodward et al. [481] successfully completed the total synthesis of erythromycin by using S Pyrm glycoside of D-desosamine and S Pyr-glycoside of L-cladinose as glycosyl donors to the subsequent glycosylation with erythronalide A. This methodology was also successfully used in the synthesis of oleandomycin [482,483], erythromycin A [484] and erythromycin B [485].
