With depleting conventional energy sources there is urgent need to look for alternatives automotive fuel especially from Non-edible feedstocks. Present work investigates FAME (fatty acids methyl esters) synthesis commonly known as Biodiesel non-edible feedstock Karanja using heterogeneous catalyst calcium oxide (CaO). Study was investigated considering effects of oil-methanol mole ratio, concen...

In the enanti-opure crystal of the title compound, C(4)H(10)NO(3) (+)·Cl(-), inter-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds link the mol-ecules into layers parallel to (001).

This study evaluated the effects of progressive nitric oxide (NO) inhibition in the regulation of systemic and regional hemodynamics and renal function in anesthetized dogs. The N(G)-nitro-L-arginine methyl ester group (n = 9) received progressive doses of 0.1, 1, 10, and 50 microg. kg(-1). min(-1). Renal (RBF), mesenteric (MBF), iliac (IBF) blood flows, mean arterial pressure (MAP), pulmonary ...

UNLABELLED Cyclooxygenase (COX)-1 and -2 are prostanoid-synthesizing enzymes that play important roles in the regulation of neuroinflammation and in the development of neurodegenerative disorders. However, the specific functions of these isoforms are still unclear. We recently developed (11)C-labeled ketoprofen methyl ester as a PET probe that targets the COXs for imaging neuroinflammation, tho...

During the second hour after giving 100 ,ug of orally administered prostaglandin 15 (R) 15-methyl-E, methyl ester in the pregnant patient at term a noticeable reduction in basal gastric acid secretion took place. At this dose no excessive uterine stimulation was observed. Prostaglandin 15 (R) 15-methyl-E, methyl ester could prove of value in the preoperative preparation of the pregnant patient ...

Some antimony complexes of a new class of substituted thioimines have been prepared by reacting Ph3Sb (III) with [1-(2-naphthyl) ethyledene] hydrazinecarbodithioic acid phenyl methyl ester (LH), [1-(2-thienyl) ethyledene] hydrazinecarbodithioic acid phenyl methyl ester (LH), [1-(2-pyridine) ethyledene] hydrazinecarbodithioic acid phenyl methyl ester (LH) and [1-(2-furanyl)ethyledene] hydrazinec...

1. Glutamate dehydrogenase was inhibited by l-serine O-sulphate, beta-chloro-l-alanine, O-phospho-l-serine and beta-chloro-l-alanine methyl ester. With the exception of beta-chloro-l-alanine methyl ester which was an irreversible inhibitor, it was possible to reverse the inhibitory effects by dialysis. 2. Both NAD(+) and glutamate afford some protection against the inhibition due to the methyl ...

An earlier proposed endoperoxide intermediate in the biosynthesis of prostaglandins was detected in short-time incubations of arachidonic acid with the microsomal fraction of homogenates of sheep vesicular glands. Conversion of the endoperoxide into prostaglandin E(2) was stimulated by reduced glutathione but suppressed by p-mercuribenzoate and N-ethylmaleimide. The methyl ester of an unknown c...

We have isolated glutamic acid 5-methyl ester from an Escherichia coli protein that is involved in chemotaxis. The bacteria were first incubated with [methyl-“Hlmethionine under conditions which are known to result in methylation of the protein. The protein, isolated by gel electrophoresis, was then digested by successive treatment with three proteolytic enzymes. One of the products was [methyl...

This work was to find out the dominant secondary metabolites derived from the fungus Trichoderma and to test them against skin cancer protein. The metabolites were extracted in 80% methanol from the fungal biomass of Trichoderma isolated from mangrove sediment. The crude methanol extract was purified and analysed for the secondary metabolites by GC-MS. Three predominant compounds (heptadecanoic...
