Combined biotransformations of 4(20),11-taxadienes

, : Combined biotransformations of 4(20),11-taxadienes. Tetrahedron 61(23): 5507-5517

Taxuyunnanine C (1) and its analogs (2 and 3), the C-14 oxygenated 4(20), 11-taxadienes from callus Cultures of Taxus sp., were regio- and stereo-selectively hydroxylated at the 7 beta position by a fungus, Abisidia coerulea IFO 4011, and it was interesting that the longer the alkyl chain of the acyloxyl group at C-14 became, the higher the yield of 7 beta-hydroxylated product was.

The microsomal NADH- and the ascorbate-dependent fatty acid desaturation are diminished by monodehydroascorbate. This effect can be neutralized by borate. Borate forms an adduct with didehydroascorbate and prevents the formation of monodehydroasco...

The susceptibility of A. gossypii infesting cotton to endosulfan, monocrotophos, phosphamidon, dimethoate, acephate and cypermethrin was determined. Alongside this, the toxicity of the aphid to new insecticides (diafenthiuron, imidacloprid, acetam...

The activity of the plasmalemmal Na<sup>+</sup>/Ca<sup>2+</sup> exchanger (NCX) is highly sensitive to temperature. We took advantage of this fact to explore here the effects of the NCX blocker KB-R7943 (KBR) at 22 and 37&d...

The nuclear receptors REV-ERB alpha (encoded by NR1D1) and REV-ERB beta (NR1D2) have remained orphans owing to the lack of identified physiological ligands. Here we show that heme is a physiological ligand of both receptors. Heme associates with t...
