Potentiation of cADPR-induced Ca2+-release by methylxanthine analogues

Caffeine and other methylxanthines are known to induce Ca2+-release from intracellular stores via the ryanodine receptor. In the present work, a range of caffeine analogues, in which methyl groups at the 1 and 7 positions were replaced with alkyl chains containing different functional groups (oxo, hydroxyl, propargyl, ester, and acids), were synthesized. These compounds were then screened for their ability to potentiate Ca2+-release induced by cADPR (an endogenous modulator of ryanodine receptors) in sea urchin egg homogenates. Two of the synthesized methylxanthines, 1,3-dimethyl-7-(7- hydroxyoctyl)xanthine (37) and 3-methyl-7-(7-oxooctyl)-1-propargylxanthine (66), were shown to be more potent than caffeine in potentiating cADPR- induced Ca2+-release, while 1,3-dimethyl-7-(5-ethylcarboxypentyl)xanthine (14) was shown to be more efficacious. The development of new methylxanthine analogues may lead to a better understanding of ryanodine receptor function and could possibly provide novel therapeutic agents.

Total synthesis of antibiotic karnamicin B1

The novel antifungal karnamicin B1 (1), 5-hydroxy-3,4-dimethoxy-2-{2-(4-oxopentyl)-4-thiazolyl}pyridine-6-carboxamide was first synthesized via the formation of partially methylated trihydroxy pyridine by ring-transformation from the corresponding furan derivative and subsequent regioselective introduction of 2,6-substituents using Meisenheimer-type reaction.

INSECT PHEROMONES AND THEIR ANALOGS. XLVII. SYNTHESIS OF 11-OXODODECA-3,6-DIYNOIC ACID - THE ACYCLIC PRECURSOR OF A MACROLIDE COMPONENT OF PHEROMONES OF Oryzaephilus mercator AND O. surinamensis

A new approach is proposed to the synthesis of 11-oxododeca-3,6-diynoic acid - the acyclic precursor of a macrolide component of pheromones of Oryzaephilus mercator and O. surinamensis - from the readily available tetrahydropyran or allylacetone via the intermediate 5-bromo-2,2-ethylenedioxypentane.

OZONOLYSIS OF ALKENES AND REACTIONS OF POLYFUNCTIONAL COMPOUNDS. XXXII. SYNTHESIS OF (ξ)-3,7-DIMETHYL-2,7-OCTADIENYL PROPIONATE

3,7-Dimethyl-2,7-octadien-1-ol (with the E and Z isomers in a ratio of 85:15) was obtained by the ozonolysis of 1-methyl-1-cyclopentene and subsiquent selective transformation of the 1,1-dimethoxy-5-oxohexane, including ethoxycarbonylolefination and methylenation of the carbonyl groups and reduction of the ester group.The propionate of the product is a component of the sex pheromone of the San Jose scale insect.
