Ladderane lipids produced by anammox bacteria constitute some of the most structurally fascinating yet poorly studied molecules among biological membrane lipids. Slow growth of the producing organism and the inherent difficulty of purifying complex lipid mixtures have prohibited isolation of useful amounts of natural ladderane lipids. We have devised a highly selective total synthesis of ladderane lipid tails and a full phosphatidylcholine to enable biophysical studies on chemically homogeneous samples of these molecules. Additionally, we report the first proof of absolute configuration of a natural ladderane.
Synthesis of novel mono and bis-indole conduritol derivatives and their α/β-glycosidase inhibitory effects
Cavdar, Hueseyin,Talaz, Oktay,Ekinci, Deniz
, p. 7499 - 7503 (2013/02/22)
Here we synthesized four novel indole conduritol derivatives 1-4 for the first time in the literature and probed their biological activities with the α and β-glucosidases. The compounds showed quite effective glucosidase inhibitory action. IC50

experimental part, p. 695 - 702 (2010/08/03)
A variety of novel cyano-cyclitols possessing complex stereochemistry have been synthesized. These compounds were subjected to the biocatalyzed hydrolysis of their nitrile groups. The bacterial strain Rhodococcus erythropolis A4, expressing a nitrile hydr

scheme or table, p. 2448 - 2454 (2011/02/22)
A new route to synthesize cyclophellitol and epi-cyclophellitol from racemic starting materials in enantiopure forms has been developed. The synthesis involves a multi-enzymatic biotransformation pathway of the novel cyano-cyclitol (1R,4S,5R,6R)/(1S,4R,5S
Asymmetric induction of conduritols via AAA reactions: Synthesis of the aminocyclohexitol of hygromycin A
Trost, Barry M.
, p. 1619 - 1629 (2007/10/03)
Two synthetic routes towards the construction of the aminocyclohexitol moiety of hygromycin A have been developed based on palladium-catalyzed asymmetric alkylation of conduritol derivatives. A protocol has been established whereby this biologically relev
