In the present study, some isoxazole-(benz)azole derivatives (3a-3j) were synthesized by considering antimicrobial and anticancer potencies of azole compounds. Chemical structures of obtained compounds (3a-3j) were confirmed by the data of spectral and elemental analyses. Anticancer activity evaluation was performed at two steps. Initially, cytotoxic effects of the compounds (3a-3j) on HT-29 (colon carcinoma) and C-6 (melanoma) cell lines were determined by MTT assay. Secondly, the compounds 3g-3i, which indicated significant cytotoxicity were selected and analysed for their inhibitory activity on DNA synthesis of carcinogenic cells. The compounds 3g and 3h showed notable DNA synthesis inhibition on both cancer cell lines. Antibacterial and antifungal activities of the synthesized compounds (3a-3j) were also examined. All of the compounds exhibited very poor antibacterial activity against gram negative and gram positive bacterial strains, whereas antifungal activity of the compounds 3a-3f was equal to that of Ketoconazole.

The behaviour on protonation of a series of 3-, 4-, and 5-aminoisoxazoles has been studied by 15N n.m.r. spectroscopy.The results confirm that the first protonation site in the 3- and 5-amino derivatives is located at the endocyclic nitrogen atom, while in 4-amino derivatives it is at the exocyclic nitrogen.In addition, the protonation of 3-, 4-, and 5-amino substituted 1-methyl- and 1-phenyl-pyrazoles has been investigated by an integrated u.v. and 15N n.m.r. approach.The first protonation site in the 5-amino derivatives is the pyridine-like endocyclic nitrogen, while in the 4-amino derivatives it is the exocyclic nitrogen.The 3-amino series behaves exceptionally because a tautomeric equilibrium is possible between the endocyclic and exocyclic monocations.In sulphuric acid the position of this equilibrium is dependent on H2SO4 concentration.Diprotonation of these derivatives in concentrated sulphuric acid solutions has also been studied.

Tuberculosis (TB) is one of the world’s oldest and deadliest diseases, killing a person every 20 s. InhA, the enoyl-ACP reductase from Mycobacterium tuberculosis, is the target of the frontline antitubercular drug isoniazid (INH). Compounds that directly target InhA and do not require activation by mycobacterial catalase peroxidase KatG are promising candidates for treating infections caused by INH resistant strains. The application of the encoded library technology (ELT) to the discovery of direct InhA inhibitors yielded compound 7 endowed with good enzymatic potency but with low antitubercular potency. This work reports the hit identification, the selected strategy for potency optimization, the structure-activity relationships of a hundred analogues synthesized, and the results of the in vivo efficacy studies performed with the lead compound 65.

Sulfamethoxazole (SMX), an extensively prescribed or administered antibiotic pharmaceutical product, is usually detected in aquatic environments, because of its incomplete metabolism and elimination. This study investigated the effects of exogenous cofactors on the bioremoval and biotransformation of SMX by Alcaligenes faecalis. High concentration (100 mg·L-1) of exogenous vitamin C (VC), vitamin B6 (VB6) and oxidized glutathione (GSSG) enhanced SMX bioremoval, while the additions of vitamin B2 (VB2) and vitamin B12 (VB12) did not significantly alter the SMX removal efficiency. Globally, cellular growth of A. faecalis and SMX removal both initially increased and then gradually decreased, indicating that SMX bioremoval is likely dependent on the primary biomass activity of A. faecalis. The decreases in the SMX removal efficiency indicated that some metabolites of SMX might be transformed into parent compound at the last stage of incubation. Two transformation products of SMX, N-hydroxy sulfamethoxazole (HO-SMX) and N4-acetyl sulfamethoxazole (Ac-SMX), were identified by a high-performance liquid chromatograph coupled with mass spectrometer. High concentrations of VC, nicotinamide adenine dinucleotide hydrogen (NADH, 7.1 mg·L-1), and nicotinamide adenine dinucleotide (NAD+, 6.6 mg·L-1), and low concentrations of reduced glutathione (GSH, 0.1 and 10 mg·L-1) and VB2 (1 mg·L-1) remarkably increased the formation of HO-SMX, while VB12 showed opposite effects on HO-SMX formation. In addition, low concentrations of GSH and NADH enhanced Ac-SMX formation by the addition of A. faecalis, whereas cofactors (VC, VB2, VB12, NAD+, and GSSG) had no obvious impact on the formation of Ac-SMX compared with the controls. The levels of Ac-SMX were stable when biomass of A. faecalis gradually decreased, indicating the direct effect of biomass on the formation of Ac-SMX by A. faecalis. In sum, these results help us understand the roles played by exogenous cofactors in eliminating SMX by A. faecalis and provide potential strategies for improving SMX biodegradation.

Sulfonamide antibiotics have aroused increasing concerns due to their ability to enhance the resistance of pathogenic bacteria and promote the spread of antibiotic resistance. Biodegradation plays an important role in sulfonamide dissipation in both natural and engineered ecosystems. In this article, we provided an overview of sulfonamide biodegradation in different systems and summarized the relevant sulfonamide-degrading species and metabolic pathways. The removal of sulfonamides depends on a variety of factors, such as the type and initial concentration of sulfonamides, the properties of water or soil, and treatment process. The removal efficiency of sulfonamides by engineered ecosystems can be improved by optimizing their operating conditions. Much higher sulfonamide removal was also observed in upgraded or advanced treatment systems than in conventional activated sludge systems. Ammonia oxidation might promote sulfonamide biodegradation. In addition, sulfonamide-degraders from different bacterial genera have been isolated and classified, but no bioaugmentation practice has been reported. Different pathways have been detected in sulfonamide biodegradation. Further efforts will be necessary to elucidate in-situ degraders and the metabolic pathways and functional genes of sulfonamide biodegradation.
