Synthesis, anticancer and antioxidant activities of some novel N-(benzo[d]oxazol-2-yl)-2-(7- or 5-substituted-2-oxoindolin-3-ylidene) hydrazinecarboxamide derivatives

A series of N-(benzo[d]oxazol-2-yl)-2-(7- or 5-substituted-2-oxoindolin-3- ylidene) hydrazinecarboxamide derivatives were synthesized by treating N-(benzoxazol-2-yl)hydrazinecarboxamide with different isatin derivatives. The newly synthesized compounds were characterized on the basis of spectral analyses. All the synthesized derivatives (Va-l) were screened for anticancer and antioxidant activities. The results showed the anticancer activity of test compounds against HeLa, IMR-32 and MCF-7 cancer cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. All the synthetic compounds produced a dose-dependant inhibition of growth of the cells. The IC50 values of some compounds were comparable with standard anticancer agent, cisplatin. All the title compounds effectively scavenged the free radical, alpha,alpha-diphenyl-beta-picryl hydrazyl. The test compounds having substitution with different halides (electron withdrawing groups) at C5 position showed more potent anticancer and antioxidant activities than those at C7 position. These results indicate that C5-substituted derivatives may be useful for developing antioxidant agents that play a protective role in many pathological conditions such as cancer, diabetes and so on.

Mechanism of Asymmetric Production of L-Aromatic Amino Acids from the Corresponding Hydantoins by Flavobacterium sp.

The mechanism of asymmetric production of L-aromatic amino acids from the corresponding hydantoins by Flavobacterium sp.AJ-3912 was examined by investigating the properties of the enzymes involved in the hydrolysis of 5-substituted hydantoins corresponding to aromatic amino acids (AAH).The enzymatic hydrolysis of AAH by Flavobacterium sp.AJ-3912 consisted of the following two successive reactions; a hydrolytic ring opening reaction of DL-AAH to L- and D-form N-carbamyl aromatic amino acids (NCA), involving an enzyme (hydantoin hydrolase) followed by a hydrolytic cleaving reaction of the L-form NCA to L-aromatic amino acids involving another enzyme (N-carbamyl-L-aromatic amino acid hydrolase, abbreviated as L-NCA hydrolase).The ring opening reaction involving hydantoin hydrolase was not stereospecific, but the NCA cleaving reaction involving L-NCA hydrolase was completely L-specific.The pathway for the conversion of the by-produced D-form NCA to L-aromatic amino acids was as follows; conversion of D-form NCA to D-AAH through the reverse reaction of hydantoin hydrolase, and then conversion of the D-AAH to L-AAH through spontaneous racemization, followed by the successive hydrolysis of the L-AAH to L-aromatic amino acids by hydantoin hydrolase and L-NCA hydrolase.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2008-04-0, help many people in the next few years.Recommanded Product: 2008-04-0

The effect of broccoli in diet on the cytochrome P450 activities of tilapia fish (Oreochromis niloticus) during phenol exposure

Aquaculture is the fastest growing animal food-producing sector and represents around 40% of global fish production. Doubtless, aquaculture will be soon the main world source of marine and freshwater food, over the capture fishery. Water pollution is a main concern for production and represents a public health risk. Cruciferous vegetables, as broccoli, have been reported to have a chemoprotection capacity against the effect of pollutants on different organisms. Broccoli and its phytochemicals are able to modulate the cytochrome P450 enzymes (CYP) which are involved in the xenobiotic metabolism. In this work, the effect of a broccoli-rich diet on different cytochromes P450 activities in liver from tilapia juveniles exposed to phenol was determined. Activities on phenacetin, chlorzoxazone, tolbutamide, mephenytoin, dextromethorphan, and testosterone, were monitored in tilapia liver extracts from fish fed with and without enriched broccoli diets, before and after phenol exposure. Fish were fed with broccoli and control diets during 30 days prior to phenol exposure at two sub-lethal concentrations of phenol (2 and 20 mg L-1), then the profile of CYP activities was determined at 0, 12 and 24 h after phenol addition. Before phenol addition fish fed with broccoli-rich diet showed a significant induction of phenacetin and tolbutamide activities when compared with liver extracts from fish fed with control diet. After phenol exposure a clear and steady induction of the dextromethorphan and mephenytoin activities were detected. In spite of the fact that substrates are not specific for each CYP, the increase of activity on dextromethorphan could represent the first report of a hepatic CYP2D6 induction by the presence of a xenobiotic. In addition, phenol exposure through diet was evaluated. Consistently with the previous experiments, phenacetin and chlorzoxazone showed higher activities while dextromethorphan and testosterone activities were lower in the liver extract from fish fed with broccoli than in control fish. Interestingly, tolbutamide activity was significantly higher in fish fed with broccoli than these observed in the controls, while mephenytoin showed 8-times higher activity in fish fed with control diet than those fed with broccoli enriched diet. The role of cytochrome P450 enzymes in the xenobiotic metabolism and the potential use of designed diets, containing chemoprotectors, to contend against pollutant effects on cultivated fish are discussed.

Ultrasensitive quantification of the CYP2E1 probe chlorzoxazone and its main metabolite 6-hydroxychlorzoxazone in human plasma using ultra performance liquid chromatography coupled to tandem mass spectrometry after chlorzoxazone microdosing

Chlorzoxazone is a probe drug to assess cytochrome P450 (CYP) 2E1 activity (phenotyping). If the pharmacokinetics of the probe drug is linear, pharmacologically ineffective doses are sufficient for the purpose of phenotyping and adverse effects can thus be avoided. For this reason, we developed and validated an assay for the ultrasensitive quantification of chlorzoxazone and 6-hydroxychlorzoxazone in human plasma. Plasma (0.5 mL) and liquid/liquid partitioning were used for sample preparation. Extraction recoveries ranged between 76 and 93% for both analytes. Extracts were separated within 3 min on a Waters BEH C18 Shield 1.7 mum UPLC column with a fast gradient consisting of aqueous formic acid and acetonitrile. Quantification was achieved using internal standards labeled with deuterium or 13C and tandem mass spectrometry in the multiple reaction monitoring mode using negative electrospray ionization, which yielded lower limits of quantification of 2.5 pg mL-1, while maintaining a precision always below 15%. The calibrated concentration ranges were linear for both analytes (2.5-1000 pg mL-1) with correlation coefficients of >0.99. Within-batch and batch-to-batch precision in the calibrated ranges for both analytes were <15% and <11% and plasma matrix effects always were below 50%. The assay was successfully applied to assess the pharmacokinetics of chlorzoxazone in two human volunteers after administration of single oral doses (2.5-5000 mug). This ultrasensitive assay allowed the determination of chlorzoxazone pharmacokinetics for 8 h after microdosing of 25 mug chlorzoxazone.
