Plakoside A (1) {(2S,3R,11R*,12S*)-2-[(2? R,5? Z,11? R*, 12? S*)-2?-hydroxy-11?, 12?-methylene-5?-docosen-amido]-1-O-[2?-O- (3?-methyl-2?-butenyl)-beta-D-galactopyranosyl]-11,12- methylene-1,3-docosanediol} is a prenylated galactosphingolipid isolated as an immunosuppressant from the marine sponge Plakortis simplex. (2S,3R,11S,12R,2? R,5? Z,11? S,12? R)-Plakoside A (1) has been synthesized by combining the sphingosine part 16, the alpha-hydroxy acid part 28, and the prenylated sugar part 33. (2S,3R,11R,12S,2? R,5? Z,11? R,12? S)-Plakoside A (1?) has also been synthesized.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Tetrahydropyrans, you can also check out more blogs about31608-22-7

Marine oil-spills have a long-lasting impact on the environment; therefore, it is a major concern in the scientific community to find a solution for remediation. Recently, phase selective organo-gelators emerged as potential materials for removal of oil from water through selective gelation. Herein, we report synthesis of a series of C-6 triazole linked N-acetylglucosamine derivatives, among which three have shown excellent selective gelation of organic solvents, diesel, petrol, and crude oils in water and seawater. We have studied phase selective gelation against different API grade crude oils (from light to heavy), and the gelation was achieved using nontoxic carrier solvent at room temperature in less than 15 min, and gelators were found useful for recovering crude oils. Critical gel concentration (CGC) of crude oil gelators was found to be 2.3-12% (w/v). The variable temperature NMR and FTIR experiments reveal that intermolecular hydrogen bonding was responsible for gel formation. Furthermore, a gelator was utilized for selective dye removal from water.

A 1,3,4-benzotriazepine was identified as a suitable lead in our effort toward obtaining a non-peptide parathyroid hormone-1 receptor (PTH1R) antagonist. A process of optimization afforded derivatives displaying nanomolar PTH1R affinity, a representative example of which behaved as a PTH1R antagonist in cell-based cyclic adenosine monophosphate (cAMP) assays, with selectivity over PTH2 receptors.

The natural fatty acids (5Z)-5-pentacosenoic and (9Z)-9-pentacosenoic acids were synthesized for the first time in eight steps starting from either 4-bromo-1-butanol or 8-bromo-1-butanol and in 20-58 % overall yields, while the novel fatty acids 5-pentacosynoic and 9-pentacosynoic acids were also synthesized in six steps and in 34-43 % overall yields. The ?5 acids displayed the best IC50’s (24-38 muM) against the HIV-1 reverse transcriptase (RT) enzyme, comparable to nervonic acid (IC50 = 12 muM). The ?9 acids were not as effective towards HIV-RT with the (9Z)-9-pentacosenoic acid displaying an IC50 = 54 muM and the 9-pentacosynoic acid not inhibiting the enzyme at all. Fatty acid chain length and position of the unsaturation was important for the observed inhibition. None of the synthesized fatty acids were toxic (IC50 > 500 muM) towards peripheral blood mononuclear cells. Molecular modeling studies indicated the structural determinants underlying the biological activity of the most potent compounds. These results provide new insights into the structural requirements that must be present in fatty acids so as to enhance their inhibitory potential towards HIV-RT.

Primaquine (PQ) is the only drug used to prevent relapse of malaria due to P. vivax and P. ovale, by eradicating the dormant liver form of the parasite (hypnozoites). The side-effects associated with PQ limits is uses in treatment of malaria. To overcome the premature oxidative deamination and to increase the life span of drug in the biological system, the novel glyco-conjugates of PQ were synthesized by coupling of primaquine with hexoses in phosphate buffer. The saccharide part of the hybrid molecules thought to direct the drug to the liver, where hypnozoites resides. All the synthesized compounds were fully characterized and evaluated for their radical curative activities. The three compounds viz glucoside (15a), galactoside (15b) and mannoside (15c) with high activity were tested for their activity in rhesus monkeys where the most active compound 15b showed twofold activity (100% radical curative activity at 1.92?mmol/kg) than the standard drug PQ diphosphate (3.861?mmol/kg). It is proposed that results from these studies may be advantageous to develop a new potent tissue schizonticide antimalarial compound.

A series of 5-alkenyl and 6-alkenyl aldehydes bearing aryl and ester functionality on the alkene and with and without 1,3-dioxolane substitution at the 3-position has been prepared.The N-methyl and N-benzyl nitrones derived by the condensation of the aldehydes with the corresponding hydroxylamines undergo intramolecular 1,3-dipolar cycloaddition on heating (or at room temperature in two instances) to give either bridged or fused isoxazolidines depending on the regiochemistry of the cycloaddition reaction.The 6-alkenyl nitrones give fused products in all cases except those bearing an aryl group at C-6, which give bridged products.All of the 5-alkenyl nitrones prepared in this study cyclized to afford fused isoxazolidines.
