Gas-phase and particulate products from the atmospheric degradation of an isoxazole fungicide

The isoxazole structure is present in several pesticides. However, there is a lack of information about its degradation products after the release to the atmosphere. The main atmospheric reactions of hymexazol (5-methylisoxazol-3-ol), selected as representative model, were investigated at a large outdoor simulation chamber. The predominant products of atmospheric degradations were gaseous nitrogen derivates (nitric acid, nitrogen dioxide, nitrogen oxide, nitrous acid, and peroxyacetylnitrate), ozone, and small oxygenated compounds (formic acid, formaldehyde, and methylglyoxal). The aerosol yields were lower than 5%, and an OH rate-dependence was observed in the nucleation, particle growth, and size distribution. Also, the chemical composition of minor multi-oxygenated products was studied for OH-photo-oxidations. More than 20 products were detected in the gas or particulate phase. The most abundant were heterocyclic cleavage products with C4-chain and oxygenated moieties at positions 1 and 3, such as 3,4-dioxobutanoic acid, 3-oxobutanoic acid, and 3-oxobutanal. The suggested reaction pathway is the opening of heterocycle ring by the cleavage of N-O bond and C-N bond, releasing nitrogen oxides.

Aim: Synthesis of novel glutathione S-transferases (GSTs) inhibitors constitutes a promising strategy in cancer treatment. Results & methodology: A new set of benzimidazoles clubbed with various heterocycles as GST inhibitors and anticancer agents were synthesized. The biological results proved the potential of the new compounds as GST inhibitors, specifically compounds 7 and 14 which produced more potency than ethacrynic acid by three- A nd tenfold, respectively. Most compounds exhibited promising cytotoxic activity against breast and colon cancer cell lines. Molecular modeling studies revealed that compounds 7 and 14 showed good binding with the amino acids of the GST protein. Conclusion: Both compounds 7 and 14 fulfilled the Lipinski’s rule of five suggesting them as new promising GST inhibitors and anticancer agents.

Discovery of a Series of 5-Azaquinazolines as Orally Efficacious IRAK4 Inhibitors Targeting MyD88L265P Mutant Diffuse Large B Cell Lymphoma

In this article, we report the discovery of a series of 5-azaquinazolines as selective IRAK4 inhibitors. From modestly potent quinazoline 4, we introduced a 5-aza substitution to mask the 4-NH hydrogen bond donor (HBD). This allowed us to substitute the core with a 2-aminopyrazole, which showed large gains in cellular potency despite the additional formal HBD. Further optimization led to 6-cyanomethyl-5-azaquinazoline 13, a selective IRAK4 inhibitor, which proved efficacious in combination with ibrutinib, while showing very little activity as a single agent up to 100 mg/kg. This contrasted to previously reported IRAK4 inhibitors that exhibited efficacy in the same model as single agents and was attributed to the enhanced specificity of 13 toward IRAK4.

Design, Synthesis, Molecular Modeling, and Biological Evaluation of Novel Amine-based Histone Deacetylase Inhibitors

Histone deacetylases (HDACs) are promising drug targets for a variety of therapeutic applications. Herein we describe the design, synthesis, biological evaluation in cellular models of cancer, and preliminary drug metabolism and pharmacokinetic studies (DMPK) of a series of secondary and tertiary N-substituted 7-aminoheptanohydroxamic acid-based HDAC inhibitors. Introduction of an amino group with one or two surface binding groups (SBGs) yielded a successful strategy to develop novel and potent HDAC inhibitors. The secondary amines were found to be generally more potent than the corresponding tertiary amines. Docking studies suggested that the SBGs of tertiary amines cannot be favorably accommodated at the gorge region of the binding site. The secondary amines with naphthalen-2-ylmethyl, 5-phenylthiophen-2-ylmethyl, and 1H-indol-2-ylmethyl (2 j) substituents exhibited the highest potency against class I HDACs: HDAC1 IC50 39?61 nm, HDAC2 IC50 260?690 nm, HDAC3 IC50 25?68 nm, and HDAC8 IC50 320?620 nm. The cytotoxicity of a representative set of secondary and tertiary N-substituted 7-aminoheptanoic acid hydroxyamide-based inhibitors against HT-29, SH-SY5Y, and MCF-7 cancer cells correlated with their inhibition of HDAC1, 2, and 3 and was found to be similar to or better than that of suberoylanilide hydroxamic acid (SAHA). Compounds in this series increased the acetylation of histones H3 and H4 in a time-dependent manner. DMPK studies indicated that secondary amine 2 j is metabolically stable and has plasma and brain concentrations >23- and >1.6-fold higher than the IC50 value for class I HDACs, respectively. Overall, the secondary and tertiary N-substituted 7-aminoheptanoic acid hydroxyamide-based inhibitors exhibit excellent lead- and drug-like properties and therapeutic capacity for cancer applications.
