benzaldehyde/hypoxia

In this article, we report a series of benzaldehyde thiosemicarbazone derivatives possessing high activity toward actively replicating Mycobacterium tuberculosis strain with minimum inhibitory concentration (MIC) values in the range from 0.14 to 2.2 μM. Among them, two

A series of diaryl and alkylaryl sulfoxide-containing nitrogen mustards were synthesized and evaluated for their hypoxia-selective cytotoxicity against V-79 cells in vitro as well as for their metabolism profiles with the rat S-9 fractions. In general, the diaryl sulfoxides (4, 5, and 7-9) showed

To evaluate the antiallergic effects of oral benzaldehyde in a murine model of allergic asthma and rhinitis, we divided 20 female BALB/c mice aged 8-10 weeks into nonallergic (intraperitoneally sensitized and intranasally challenged to normal saline), allergic (intraperitoneally sensitized and

Adaptation to hypoxia requires compensatory mechanisms that affect O2 transport and utilization. Decreased hemoglobin (Hb) O2 affinity is considered part of the physiological adaptive process to chronic hypoxia. However, this study explores the hypothesis that increased Hb O2 affinity can complement

The O2 dependence of the metabolism of benzylamine to benzaldehyde, benzoate and hippurate was studied in isolated rat hepatocytes. The initial oxidation to benzaldehyde, catalyzed by monoamine oxidase, had an apparent Kmo2 value of 34 microM in cells and 40 microM in isolated rat liver

The effect of the substituted benzaldehyde BW12C on haemoglobin-oxygen binding affinity, tumour radiation response and blood perfusion were investigated in a C3H mouse mammary carcinoma grown in the feet of CDF1 mice. Mouse P50 (partial pressure of oxygen at half saturation) was estimated using an

BW 12C, a substituted benzaldehyde, stabilises haemoglobin in the oxy-conformation and has attracted interest as an anti-sickling agent. The drug causes a left shift in the oxygen saturation curve and may induce tumour anoxia and enhance the effect of cytotoxic drugs. During clinical trials in

To evaluate the metabolic capacity of intact guinea pig liver under normoxic and hypoxic conditions, oxidative and reductive metabolism of diphenyl sulfoxide (DPSO) was studied by the nonrecirculating perfusion method in situ. DPSO was exclusively converted into diphenyl sulfone (DPSO2), an
