3405-77-4, Name is 5-Methylisoxazole-3-carboxylic acid, belongs to Isoxazoles compound, is a common compound. 3405-77-4In an article, authors is Aktories, once mentioned the new application about 3405-77-4.

In hamster adipocyte ghosts, the influence of the antilipolytic agents, nicotinic acid, 5-methyl-pyrazine-2-carboxylic acid 4-oxide (acipimox) and various related compounds, was studied on adenylate cyclase and low K(m) GTPase activities. As shown for hormonal factors and nicotinic acid, the new drug, acipimox, inhibited adenylate cyclase by a GTP-dependent process, which was amplified by sodium ions; half-maximal inhibition occurred at about 10 mumol/l acipimox. For the various compounds studied, the following rank order of potency in inhibition of adenylate cyclase was obtained: nicotinic acid > 3-carboxy-5-methylpyrazole > acipimox > 3-carboxy-5-methylisoxazole; 6-hydroxynicotinic acid and beta-pyridylcarbinol had no effect up to 300 mumol/l. In the same membrane system the antilipolytic drugs increased GTP hydrolysis by stimulation of a low K(m) GTPase as shown for antilipolytic hormones. The potency order of the antilipolytic agents studied was identical for GTPase stimulation and adenylate cyclase inhibition. The data suggest that the antilipolytic drugs studied act on adipocyte adenylate cyclase via membrane-bound receptors in a hormone-like manner and that stimulation of a high affinity GTPase is involved in the mechanism of adenylate cyclase inhibition by these agents.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32326-25-3, Name is 5-Methoxyisoxazol-3-amine, molecular formula is C4H6N2O2, 32326-25-3. In a Article, authors is Tatsuta£¬once mentioned of 32326-25-3

A Z-isomer (4) of 2-(5-amino-1,2,4-thiadiazol-3-yl)-2-(methoxyimino)acetic acid, which is the common acyl moiety of clinically useful cephem antibiotics, has been prepared from the aminoisoxazoles through the skeletal rearrangement in several routes. Reaction of 3-amino-5-methoxyisoxazole (7) with alkoxycarbonyl isothiocyanates gave methyl 2-(5-alkoxycarbonylamino-1,2,4-thiadiazol-3-yl)acetates (8), which were converted into the target compound 4 through the reaction of the corresponding keto ester with O-methylhydroxylamime. Compound 4 was prepared similarly from 3-aminoisoxazole (10). Also, O-methylation of 2-hydroxyimino-2-(5-methoxycarbonylamino-1,2,4-thiazol-3-yl)acetate (15) with methyl iodide or dimethyl sulfate in the presence of barium oxide and barium hydroxide octahydrate was found to afford exclusively the desired Z-isomer (14a) of methyl 2-(5-methoxycarbonylamino-1,2,4-thiadiazol-3-yl)-2-(methoxyimino)aceta te, which was led to 4.

Initial optimization of a new series of gamma-secretase modulators derived from a triterpene glycoside

The discovery of a new series of gamma-secretase modulators is disclosed. Starting from a triterpene glycoside gamma-secretase modulator that gave a very low brain-to-plasma ratio, initial SAR and optimization involved replacement of a pendant sugar with a series of morpholines. This modification led to two compounds with significantly improved central nervous system (CNS) exposure.

Synthesis of isoxazole moiety containing ferrocene derivatives and preliminarily in vitro anticancer activity

Seven new structures of an isoxazole moiety containing ferrocene derivatives (3a-3g) were firstly synthesized and characterized by 1H NMR, 13C NMR, ESI-MS. Subsequently, their in vitro anticancer activity against A549, HCT116 and MCF-7 cell lines was preliminarily evaluated using the MTT method. Among them, 3d exhibited a wide spectrum and the most potent anticancer activity against A549 and HCT116 cell lines (IC50s: 0.747 and 3.65 nM, respectively) as compared with the reference drug gefitinib (IC50s: 17.90 and 21.55 muM, respectively). 3d can be seen as the best candidate for development of anticancer drugs.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 90924-12-2 is helpful to your research. 90924-12-2

Discovery of (2 S)-8-[(3 R)-3-Methylmorpholin-4-yl]-1-(3-methyl-2-oxobutyl)-2-(trifluoromethyl)-3,4-dihydro-2 H -pyrimido[1,2- a ]pyrimidin-6-one: A novel potent and selective inhibitor of Vps34 for the treatment of solid tumors

Vps34 (the human class III phosphoinositide 3-kinase) is a lipid kinase involved in vesicle trafficking and autophagy and therefore constitutes an interesting target for cancer treatment. Because of the lack of specific Vps34 kinase inhibitors, we aimed to identify such compounds to further validate the role of this lipid kinase in cancer maintenance and progression. Herein, we report the discovery of a series of tetrahydropyrimidopyrimidinone derivatives. Starting with hit compound 1a, medicinal chemistry optimization led to compound 31. This molecule displays potent activity, an exquisite selectivity for Vps34 with excellent properties. The X-ray crystal structure of compound 31 in human Vps34 illustrates how the unique molecular features of the morpholine synthon bestows selectivity against class I PI3Ks. This molecule exhibits suitable in vivo mouse PK parameters and induces a sustained inhibition of Vps34 upon acute administration. Compound 31 constitutes an optimized Vps34 inhibitor that could be used to investigate human cancer biology.

Microwave-Assisted Metal-Free Decarboxylative Iodination/Bromination of Isoxazole-4-carboxylic Acids

A microwave-assisted metal-free route to substituted 4-haloisoxazoles via decarboxylative halogenation of substituted isoxazole-4-carboxylic acids using N-iodosuccinimide (NIS) and N-bromosuccinimide (NBS) in the presence of K3PO4 is described. It was discovered that the substitutions present at the 3-position of differently 3,5-disubstituted isoxazoles influenced the outcome of the protocol. The methodology is compatible for performing decarboxylative halogenation followed by decarboxylative Suzuki-Miyaura and Sonogashira couplings as one-pot process.
