Substituted Benzamides. 1. Potential Nondopaminergic Antagoinists of Chemotherapy-Induced Nausea and Emesis

A series of new substituted benzamides has been synthesized and evaluated for dopamine antagonist activity and for antagonism of cisplatin-induced emesis in the dog and in the ferret.It was found that modification of the 2-methoxy substituent of metoclopramide was detrimental to dopaminergic D2 antagonism but not necessarily to antagonism of cisplatin-induced emesis.A number of analogues having a beta-keto, beta-hydroxy, beta-methoxy, beta-imino, or beta-unsaturated alkyloxy substituent instead of methoxy have shown equal or superior protection from emesis to that of metoclopramide.At the same time these compounds were found to be free of dopaminergic D2 antagonism in both in vitro (<3H>spiperone binding) and in vivo tests (rat catalepsy, antagonism of apomorphine-induced stereotypy in the rat, and apomorphine-induced emesis in the dog).

Structure-activity relationships of N2-aryl-3-(isoxazolylsulfamoyl)-2- thiophenecarboxamides as selective endothelin receptor-A antagonists

We report here that N2-aryl-3-(isoxazolylsulfamoyl)-2- thiophenecarboxamides are potent and selective small molecule ET(A) receptor antagonists. The aryl group was subjected to extensive structural modification. With monosubstitution, the para position was most useful in increasing potency, with methyl being preferred. With disubstitution, 2,4- disubstitution further enhanced activity with methyl or cyano groups being preferred at the 2-position. In this series, a benzo[d][1,3]dioxole group is equivalent to a 4-methyl group in in vitro activity and afforded the compounds with both in vivo activity and moderate half-lives.

The synthesis of cyanoformamides via a CsF-promoted decyanation/oxidation cascade of 2-dialkylamino-malononitriles

A mild and efficient method for the synthesis of cyanoformamides from N,N-disubstituted aminomalononitriles with CsF as the promoter has been developed. This method features a wide substrate scope and high reaction efficiency, and will facilitate corresponding cyanoformamide-based biological studies and synthetic methodology development.

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.SDS of cas: 33282-15-4, you can also check out more blogs about33282-15-4

2,2?-Bis-substituted Biphenyls by the Addition of Nucleophiles to Benzyne Followed by in Situ Oxidative Homocoupling

The paper describes the addition of Mg-anilides and -thiolates to in situ generated benzyne with subsequent oxidative homocoupling of the adducts to give 2,2?-bis-substituted biphenyls in a one-pot process. Oxidative C-C bond formation was best achieved with a Cu catalyst using O2 as oxidant. The sequence comprises two C-X and one C-C bond formation and the products were obtained in moderate yields. Some of the 2,2?-bis-substituted biphenyls have been characterized by X-ray analysis.

Photolysis of (3-methyl-2H-azirin-2-yl)-phenylmethanone: Direct detection of a triplet vinylnitrene intermediate

The photoreactivity of (3-methyl-2H-azirin-2-yl)-phenylmethanone, 1, is wavelength-dependent (Singh et al. J. Am. Chem. Soc. 1972, 94, 1199-1206). Irradiation at short wavelengths yields 2P, whereas longer wavelengths produce 3P. Laser flash photolysis of 1 in acetonitrile using a 355 nm laser forms its triplet ketone (T1K, broad absorption with lambdamax ? 390-410 nm, tau ? 90 ns), which cleaves and yields triplet vinylnitrene 3 (broad absorption with lambdamax ? 380-400 nm, tau = 2 mus). Calculations (B3LYP/6-31+G(d)) reveal that T1K of 1 is located 67 kcal/mol above its ground state (S0) and has a long C-N bond (1.58 A), and the calculated transition state to form 3 is only 1 kcal/mol higher in energy than T1K of 1. The calculations show that 3 has significant 1,3-carbon iminyl biradical character, which explains why 3 reacts efficiently with oxygen and decays by intersystem crossing to the singlet surface. Photolysis of 1 in argon matrixes at 14 K produced ketene imine 7, which presumably is formed from 3 intersystem crossing to 7. In comparison, photolysis of 1 in methanol with a 266 nm laser produces mainly ylide 2 (lambdamax ? 380 nm, tau ? 6 mus, acetonitrile), which decays to form 2P. Ylide 2 is formed via singlet reactivity of 1, and calculations show that the first singlet excited state of the azirine chromophore (S1A) is located 113 kcal/mol above its S0 and that the singlet excited state of the ketone (S1K) is 85 kcal/mol. Furthermore, the transition state for cleaving the C-C bond in 1 to form 2 is located 49 kcal/mol above the S0of 1. Thus, we theorize that internal conversion of S1A to a vibrationally hot S0 of 1 forms 2, whereas intersystem crossing from S1K to T1K results in 3.

Adenosine monophosphate (AMP)-activated protein kinase: A new target for nutraceutical compounds

Adenosine monophosphate-activated protein kinase (AMPK) is an important energy sensor which is activated by increases in adenosine monophosphate (AMP)/adenosine triphosphate (ATP) ratio and/or adenosine diphosphate (ADP)/ATP ratio, and increases different metabolic pathways such as fatty acid oxidation, glucose transport and mitochondrial biogenesis. In this sense, AMPK maintains cellular energy homeostasis by induction of catabolism and inhibition of ATP-consuming biosynthetic pathways to preserve ATP levels. Several studies indicate a reduction of AMPK sensitivity to cellular stress during aging and this could impair the downstream signaling and the maintenance of the cellular energy balance and the stress resistance. However, several diseases have been related with an AMPK dysfunction. Alterations in AMPK signaling decrease mitochondrial biogenesis, increase cellular stress and induce inflammation, which are typical events of the aging process and have been associated to several pathological processes. In this sense, in the last few years AMPK has been identified as a very interesting target and different nutraceutical compounds are being studied for an interesting potential effect on AMPK induction. In this review, we will evaluate the interaction of the different nutraceutical compounds to induce the AMPK phosphorylation and the applications in diseases such as cancer, type II diabetes, neurodegenerative diseases or cardiovascular diseases.
