In a article, author is Han, Young Taek, introduce new discover of the category.

In the recent decades, N-heterocycles are widely used as versatile scaffolds for the development of biologically active compounds and considered as one of the privileged structures. Among the various N-heterocycles, benzodiazines, a series of bicyclic heterocycles in which benzene rings are fused with 6-membered heterocycles containing two nitrogens are especially interesting, due to their structural conciseness and usefulness as synthetic intermediates, and suitable physicochemical properties as potential drug candidates and chemical probes. For this reason, a series of synthetic methodologies for benzodiazines has been developed and generally used in organic and medicinal chemistry fields. Interestingly, synthesis of quinazoline, a kind of benzodiazine in which benzene is fused with pyrimidine, has been extensively reviewed, while cinnoline, phthalazine and quinoxaline, benzene fused with pyridazine or pyrazine, have been relatively less investigated. In this review, recent advances in the synthesis of biologically active benzodiazines, benzene ring-fused 6-membered heterocycles with two nitrogen atoms, cinnoline, phthalazine and quinoxaline, will be addressed. In each section, biological activities of various benzodiazines, recently served as novel scaffolds for drug discovery, are briefly summarized for comprehensive understanding of biological and medicinal significance in advance. Moreover, intensive investigation of the synthetic approaches to various benzodiazines such as cinnoline, phthalazine and quinoxaline is followed. It would hopefully be helpful for the readers who have interests in developing novel drug candidates and related useful chemical probes.

SDS of cas: 62-23-7, We’ll be discussing some of the latest developments in chemical about CAS: 62-23-7, Name is 4-Nitrobenzoic acid, SMILES is O=C(O)C1=CC=C([N+]([O-])=O)C=C1, belongs to phthalazine compound. In a article, author is Dong, Yong Ping, introduce new discover of the category.

A novel chemiluminescence (CL) system, including the cyclometallated iridium(III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium}, potassium permanganate and oxalic acid, is proposed for the determination of benzenediols. This method is based on the fact that hydroquinone and catechol exhibited an inhibiting effect, while resorcinol exhibited an enhancing effect on CL intensity. The optimum conditions for CL emission were investigated. Under optimal conditions, the detection limits of hydroquinone, catechol and resorcinol were 6.4?x?10-8, 2.7?x?10-9 and 8.1?x?10-7?mol/L, respectively. The method has been successfully applied to the determination of benzenediols in different types of water sample. The luminophors of the CL systems were all identified as the metalligand charge-transfer (MLCT) excited state of the iridium complex. Copyright (c) 2011 John Wiley & Sons, Ltd.
