We report structure-activity studies of a large number of dialkyl imidazoles as inhibitors of Trypanosoma cruzi lanosterol-14α-demethylase (L14DM). The compounds have a simple structure compared to posaconazole, another L14DM inhibitor that is an anti-Chagas drug candidate. Several compounds display potency for killing T. cruzi amastigotes in vitro with values of EC50 in the 0.4-10 nM range. Two compounds were selected for efficacy studies in a mouse model of acute Chagas disease. At oral doses of 20-50 mg/kg given after establishment of parasite infection, the compounds reduced parasitemia in the blood to undetectable levels, and anal. of remaining parasites by PCR revealed a lack of parasites in the majority of animals. These dialkyl imidazoles are substantially less expensive to produce than posaconazole and are appropriate for further development toward an anti-Chagas disease clin. candidate.

The sphingosine-1-phosphate-1 receptor (S1P1) and its endogenous ligand sphingosine-1-phosphate (S1P) cooperatively regulate lymphocyte trafficking from the lymphatic system. Herein, we disclose 4-methoxy-N-[2-(trifluoromethyl)biphenyl-4-ylcarbamoyl]nicotinamide (8), an uncommon example of a synthetic S1P1 agonist lacking a polar headgroup, which is shown to effect dramatic reduction of circulating lymphocytes (POC = -78%) in rat 24 h after a single oral dose (1 mg/kg). The excellent potency that 8 exhibits toward S1P1 (EC50 = 0.035 μM, 96% efficacy) and the >100-fold selectivity that it displays against receptor subtypes S1P2-5 suggest that it may serve as a valuable tool to understand the clin. relevance of selective S1P1 agonism.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 3-Bromo-4-chloronitrobenzene(SMILESS: BrC1=C(C=CC(=C1)[N+](=O)[O-])Cl,cas:16588-26-4) is researched.Reference of (R)-3-(tert-Butoxycarbonyl)-5,5-dimethylthiazolidine-4-carboxylic acid. The article 《Structure-Activity Relationships for the Glutathione Conjugation of 2-Substituted 1-Chloro-4-nitrobenzenes by Rat Glutathione S-Transferase 4-4》 in relation to this compound, is published in Chemical Research in Toxicology. Let’s take a look at the latest research on this compound (cas:16588-26-4).

In the present study structure-activity relationships (SAR’s) are described for the exptl. determined kinetic parameters (Km, kcat, and kcat/Km) of the GST 4-4-catalyzed reaction between GSH and 10 2-substituted 1-chloro-4-nitrobenzenes. Steric, lipophilic, and electronic parameters were correlated with the kinetic parameters. Moreover, charge distributions and several energy values were calculated for the substrates and the corresponding Meisenheimer intermediates with MeS- as a model nucleophile for the thiolate anion of GSH and used in the regression analyses. The correlations obtained were compared with the corresponding SAR’s for the base-catalyzed GSH conjugation reaction at pH 9.2. A high correlation coefficient was found between the kinetic parameter ks for the base-catalyzed reaction and the Hammett substituent constant (σp). Much lower correlation coefficients were obtained with kcat and σp and with kcat/Km and σp. Moreover, the reaction constant ρ was significantly higher for the base-catalyzed than for the enzyme-catalyzed reaction. Also, high correlations were found between the kinetic parameters and the charges on the p-nitro substituent in the substrates. When ks was plotted against these charges, a linear relation was found in which the slope was larger than the slope of a corresponding plot with kcat/Km. The Hammett σp can be divided into an inductive (F) and a resonance (R) component. With multiple regression between the kinetic parameters and F and R, higher correlation coefficients were obtained than with σp alone. The observations suggest that the transition states for the base-catalyzed and the GST 4-4-catalyzed GSH conjugation reaction are different. Moreover, single classical physicochem. and computer-calculated mol. parameters and combinations of them can be an alternative approach for examining SAR’s for spontaneous and GST-catalyzed GSH conjugation reactions.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

SAR for a wide variety of heterocyclic replacements for a benzimidazole led to the discovery of functionalized 2-pyridyl amides as novel inhibitors of the hedgehog pathway. The 2-pyridyl amides were optimized for potency, PK, and drug-like properties by modifications to the amide portion of the mol. resulting in I (GDC-0449). Amide I produced complete tumor regression at doses as low as 12.5 mg/kg BID in a medulloblastoma allograft mouse model that is wholly dependent on the Hh pathway for growth and is currently in human clin. trials, where it is initially being evaluated for the treatment of BCC.

Compound: 3-Bromo-4-chloronitrobenzene, is researched, Molecular C6H3BrClNO2, CAS is 16588-26-4, about 4-Substituted 1-Chloro-2-nitrobenzenes: Structure-Activity Relationships and Extension of the Substrate Model of Rat Glutathione S-Transferase 4-4.SDS of cas: 16588-26-4.

In the present study, eleven 4-substituted 1-chloro-2-nitrobenzenes were tested for their GSH conjugation capacity when catalyzed by base or rat glutathione S-transferase (GST) 4-4. Kinetic parameters (ks and Km, kcat, and kcat/Km) were determined and subsequently used for the description of structure-activity relationships (SAR’s). For this purpose, eight physicochem. parameters (electronic, steric, and lipophilic) of the substituents and five computer-calculated parameters of the substrates (charge distributions and several energy values) were used in regression analyses with the kinetic parameters. The obtained SAR’s are compared with corresponding SAR’s for the GSH conjugation of 2-substituted 1-chloro-4-nitrobenzenes, previously determined [van der Aar et al. (1996) Chem. Res. Toxicol. 9, 527-534]. The kinetic parameters of the 4-substituted 1-chloro-2-nitrobenzenes correlated well with the Hammett σp- constant: the Hammett σp constant corrected for “”through resonance”” while the corresponding kinetic parameters of the 2-substituted 1-chloro-4-nitrobenzenes did not. The base- and GST 4-4-catalyzed GSH conjugation reactions of 2-substituted 1-chloro-4-nitrobenzenes depend to a different extent on the electronic properties of the ortho substituents, suggesting the involvement of different rate-limiting transition states. The base- and GST 4-4-catalyzed conjugation of 4-substituted 1-chloro-2-nitrobenzenes, however, showed a similar dependence on the electronic properties of the para substituents, indicating that these substrates are conjugated to GSH via a similar transition state. Multiple regression analyses revealed that, besides electronic interactions, also steric and lipophilic restrictions appeared to play an important role in the GST 4-4-catalyzed GSH conjugation of 4-substituted 1-chloro-2-nitrobenzenes. Finally, the 4-substituted 1-chloro-2-nitrobenzenes were also used to extend the previously described substrate model for GST 4-4 [De Groot et al. (1995) Chem. Res. Toxicol. 8, 649-658], by which a specific steric restriction of substrates for GST 4-4 became clear.

The title compound (I) undergoes hydrolysis at 80° and pH 1.0-8.0 by acid- and base-dependent processes and by an uncatalyzed path. The uncatalyzed reaction exhibits the same characteristics as the uncatalyzed N-O bond-cleavage reactions of the more reactive N-(sulfonatooxy)acetanilides. The pH-dependent paths involve the hydrolysis of I to form N-(3-bromophenyl)hydroxylamine O-sulfonate (II). II cannot be directly detected under the conditions of this study, but its existence can be inferred from product study and trapping data. Although II undergoes decomposition entirely by heterolytic N-O bond cleavage to yield m-BrC6H4N+H (III), a less reactive analog of II, i.e., N-(3-bromophenyl)-O-pivaloylhydroxylamine (IV), apparently undergoes competitive homolytic and heterolytic N-O bond cleavage to yield both m-NHC6H4Br radical and III. Both II and IV serve as models for certain suspected carcinogenic metabolites of polycyclic aromatic amines and amides.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Nucleophilic substitution of aromatic chlorine in diazonium ions by bromide ions》. Authors are Lamm, Bo.The article about the compound:3-Bromo-4-chloronitrobenzenecas:16588-26-4,SMILESS:BrC1=C(C=CC(=C1)[N+](=O)[O-])Cl).HPLC of Formula: 16588-26-4. Through the article, more information about this compound (cas:16588-26-4) is conveyed.

To determine why a Cl atom in a suitably substituted diazonium ion should not be replaced by a Br- ion, the reaction of 2-chloro-5-nitrobenzenediazonium ion in an HBr-AcOH-H2O medium at 25° was studied. It was found that some of the aromatic Cl is “”frozen in”” and no quant. conversion of aromatic Cl to Br can occur; the reverse reactions are considerably more rapid than the forward ones, so that a small amount of Cl- ions generated in the exchange reaction produces an equilibrium containing comparable amounts of each, despite the large excess of HBr; and the equilibrium is continually being disturbed by the side-reactions, which cannot be suppressed by increasing the Br- ion concentration
