Excited-state intramolecular single and double proton transfer emission of 2,5-bis(benzoxazol-2-yl)thiophene-3,4-diol

In this work, excited-state intramolecular single proton transfer emission (S-PTE) and double proton transfer emission (D-PTE) are presented by employing 2,5-bis(benzoxazol-2-yl)thiophene-3,4-diol (1) as a prototype. 1 has been strategically designed and synthesized in an aim to explore single proton transfer and double proton transfer in the excited state. In solution 1 exhibits the lowest lying S0 ? S1 absorption at ?395 nm. Upon excitation, two large Stokes shifted emission bands maximized at 475 nm and 550 nm are resolved, which are ascribed to the tautomer emission resulting from single proton transfer and double proton transfer isomers, respectively. It is found that solvents have greatly influenced on excited-state intramolecular proton transfer emission.

Copper promoted desulfurization and C-N cross coupling reactions: Simple approach to the synthesis of substituted 2-aminobenzoxazoles and 2,5-disubstituted tetrazole amines

Copper-supported novel, facile and efficient methods for the synthesis of various 2-amino-benzoxazoles and 2,5-diphenyltetrazoleamines have been demonstrated. The reaction procedures are simple, with excellent substrate tolerance in good to high yields thus paving an excellent and useful way to establish a library of potentially active drug molecules. This methodology represents the first concept of copper-catalyst promoted domino C-N cross-coupling reaction towards the construction of 2-aminobenzoxazoles. In addition, we described report for the synthesis of 2,5-diaryltetrazoleamines using copper via inter molecular C-N cross-coupling reaction with aryl iodides. The proposed reaction mechanism involves copper based desulphurization/nucleophilic substitution and subsequent C-N cross-coupling reactions. We established numerous applications of this methodology for synthesizing diverse heterocyclic derivatives i.e. both electron rich and electron deficient systems.

Heterocyclic amidine derivatives of benzothiazole (6a-c), benzimidazole (6d-f), benzoxazole (6g-i), and bis-amidine derivatives of pyrimidine, (7a, 7b) & triazole (7c-e) ring system have been synthesized by nucleophilic addition reaction. All these compounds were screened for anti-inflammatory and anticancer activities. At a dose of 50 mg/kg p.o., compounds 6c (39%), 6e (39%), and 6f (39%) exhibited anti-inflammatory activity comparable to standard drug ibuprofen, which showed 39% activity and compounds 6b, 6e, 7a, and 7c exhibited moderate anticancer activity against cervix (HELA); neuroblastoma (IMR-32); breast (MCF-7), leukemia (THP-1); and cervix (HELA) human cancer cell lines, respectively.

Synthesis of 4-(2-hydroxyphenyl)-1-phenyl-1,2,4-triazolidine-3,5-dione derivatives through cyclic transformations of 3-(2-phenylcarbazoyl)-2(3H)-benzoxazolone derivatives

Four 3-(3-benzylidene-2-phenylcarbazoyl)-2(3H)-benzoxazolone derivatives 3 have been synthesized from benzoxazolone derivatives 1 and benzaldehyde N-chloroformylphenylhydrazone 2. By acid hydrolysis, these compounds yielded 3-(2-phenylcarbazoyl)-2(3H)benzoxazolone derivatives 4 which were not isolated and were transformed via an intramolecular reaction into 4-(2-hydroxyphenyl)-1-phenyl-1,2,4-triazolidine-3,5-dione derivatives 5 in a good yield. Attempts to cyclize these compounds by intramolecular elimination of water into tricyclic compounds 6 with various dehydrating agents were unsuccessful.

Storage stability study of porcine hepatic and intestinal cytochrome P450 isoenzymes by use of a newly developed and fully validated highly sensitive HPLC-MS/MS method

Microsomes are an ideal medium to investigate cytochrome P450 (CYP450) enzyme-mediated drug metabolism. However, before microsomes are prepared, tissues can be stored for a long time. Studies about the stability of these enzymes in porcine hepatic and intestinal tissues upon storage are lacking. To be able to investigate CYP450 stability in microsomes prepared from these tissues, a highly sensitive and rapid HPLC-MS/MS method for the simultaneous determination of six CYP450 metabolites in incubation medium was developed and validated. The metabolites, paracetamol (CYP1A), 7-hydroxy-coumarin (CYP2A), 1-hydroxy-midazolam (CYP3A), 4-hydroxy-tolbutamide (CYP2C), dextrorphan (CYP2D), and 6-hydroxy-chlorzoxazone (CYP2E) were extracted with ethyl acetate at pH?1.0, followed by evaporation and separation on an Agilent Zorbax Eclipse Plus C18 column. The method was fully validated in a GLP-compliant laboratory according to European guidelines and was highly sensitive (LOQ = 0.25?2.5?ng/mL), selective, had good precision (RSD-within, 1.0?9.1%; RSD-between, 1.0?18.4%) and accuracy (within-run, 83.3?102%; between-run, 78.5?102%), and showed no relative signal suppression and enhancement. Consequently, this method was applied to study the stability of porcine hepatic and intestinal CYP450 isoenzymes when tissues were stored at ? 80?C. The results indicate that porcine CYP450 isoenzymes are stable in tissues at least up to 4?months when snap frozen and stored at ? 80?C. Moreover, the results indicate differences in porcine CYP450 stability compared to rat, rabbit, and fish CYP450, as observed by other research groups, hence stressing the importance to investigate the CYP450 stability of a specific species.
