Studies on Synthesis of Novel Triazole Tagged Pyrazole Fused Naphthalene 5-Thiazine-5,5-dioxide Derivatives, Their Antimicrobial, and Antioxidant Activity

A series of novel triazole tagged pyrazole fused naphthalene-5-thiazine-5,5-dioxide derivatives 8 and 9 were synthesized starting from sodium salt of saccharin 1. The structure of each intermediate and products was established on the basis of spectroscopy data. All the synthesized compounds 8 and 9 were screened against various bacterial and fungal strains but found to show no activity up to 150-mu g/mL concentration. Further screening for antioxidant property resulted promising compounds.

Determination of Lipophilicity of Allyl Thiosemicarbazide, N-1-Thiocarbamylamidrazone Derivatives, and their Cyclic Products by RP-HPLC, RP-TLC, and Theoretical Methods: Effects of Selected Compounds on the CNS of Mice

The allyl thiosemicarbazide, N-1-thiocarbamylamidrazone derivatives, and the products of their cyclization: the 1,2,4-triazole, 1,3,4-thiadiazole, 1,2,4-triazole[3,4-b]1,3-thiazine, 1,2,4-triazole[3,2-b]1,3-thiazine, 1,3,4-thiadiazole[3,2-a]pyrimidine, 5,6-dihydrothiazolo[2,3-c][1,2,4]triazole, and benzoic acid derivatives have been analyzed by RP-HPLC and RP-TLC methods using the methanol-water mixtures as the mobile phase and the octadecyl stationary phase. The lipophilicity was expressed as the chromatographically derived descriptors: mean of k(mk), mean of logk (mlogk), logk(W), S, and phi(0), scores of k, logk, and R-M corresponding to the first principal component. Additionally, the authors propose to introduce a descriptor (logk(m)) corresponding to the residual specific interactions. Chromatographic parameters of lipophilicity were compared with the partition coefficient (logP) calculated by various softwares (milogP, clogP, AlogPs, AClogP, AlogP, MlogP, KOWWIN, XlogP2, XlogP3). The matrices were created with logk(W) or R-MW and logP and they have been the subject of PCA analysis. The effects of the selected compounds on the central nervous system (CNS) of mice were studied.

Pathological conformations involving the amino terminus of tau occur early in Alzheimer’s disease and are differentially detected by monoclonal antibodies

Conformational changes involving the amino terminus of the tau protein are among the earliest alterations associated with tau pathology in Alzheimer’s disease and other tauopathies. This region of tau contains a phosphatase-activating domain (PAD) that is aberrantly exposed in pathological forms of the protein, an event that is associated with disruptions in anterograde fast axonal transport We utilized four antibodies that recognize the amino terminus of tau, TNT1, TNT2 (a novel antibody), Tau12, and Tau13, to further study this important region. Using scanning alanine mutations in recombinant tau proteins, we refined the epitopes of each antibody. We examined the antibodies’ relative abilities to specifically label pathological tau in non-denaturing and denaturing assays to gain insight into some of the mechanistic details of PAD exposure. We then determined the pattern of tau pathology labeled by each antibody in human hippocampal sections at various disease stages in order to characterize PAD exposure in the context of disease progression. The characteristics of reactivity for the antibodies fell into two groups. TNT1 and TNT2 recognized epitopes within amino acids 7-12 and specifically identified recombinant tau aggregates and pathological tau from Alzheimer’s disease brains in a conformation-dependent manner. These antibodies labeled early pre-tangle pathology from neurons in early Braak stages and colocalized with thiazine red, a marker of fibrillar pathology, in classic neurofibrillary tangles. However, late tangles were negative for TNT1 and TNT2 indicating a loss of the epitope in later stages of tangle evolution. In contrast, Tau12 and Tau13 both identified discontinuous epitopes in the amino terminus and were unable to differentiate between normal and pathological tau in biochemical and tissue immunohistological assays. Despite the close proximity of these epitopes, the antibodies demonstrated remarkably different abilities to identify pathological changes in tau indicating that detection of conformational alterations involving PAD exposure is not achieved by all N-terminal tau antibodies and that a relatively discrete region of the N-terminus (i.e., amino acids 7-12, the TNT1 and TNT2 epitope) is central to the differences between normal and pathological tau. The appearance of PAD in early tau pathology and its disappearance in late-stage tangles suggest that toxic forms of tau are associated with the earliest forms of tau deposits. Collectively, these findings demonstrate that the TNT antibodies are useful markers for early conformational display of PAD and provide information regarding conformational changes that have potential implications in the toxic mechanisms of tau pathology.

10H-1,9-diazaphenothiazine and its 10-derivatives: synthesis, characterisation and biological evaluation as potential anticancer agents

10H-1,9-diazaphenothiazine was obtained in the sulphurisation reaction of diphenylamine with elemental sulphur and transformed into new 10-substituted derivatives, containing alkyl and dialkylaminoalkyl groups at the thiazine nitrogen atom. The 1,9-diazaphenothiazine ring system was identified with advanced H-1 and C-13 NMR techniques (COSY, NOESY, HSQC and HMBC) and confirmed by X-ray diffraction analysis of the methyl derivative. The compounds exhibited significant anticancer activities against the human glioblastoma SNB-19, melanoma C-32 and breast cancer MDA-MB-231 cell lines. The most active 1,9-diazaphenothiazines were the derivatives with the propynyl and N, N-diethylaminoethyl groups being more potent than cisplatin. For those two compounds, the expression of H3, TP53, CDKN1A, BCL-2 and BAX genes was detected by the RT-QPCR method. The proteome profiling study showed the most probable compound action on SNB-19 cells through the intrinsic mitochondrial pathway of apoptosis. The 1,9-diazaphenotiazine system seems to be more potent than known isomeric ones (1,6-diaza-, 1,8-diaza-, 2,7-diaza- and 3,6-diazaphenothiazine). [GRAPHICS] .
