An Approach to Polysubstituted Triazipines, Thiadiazoles and Thiazoles Based on Benzopyran Moiety Through The Utility of Versatile Hydrazonoyl Halides as In Vitro Monoamine Oxidase Inhibitors

The chromene compound 1 is used as a key intermediate for synthesis of new heterocyclic compounds, and it reacted with hydrazonoyl chlorides in presence of TEA to give the amidrazone derivatives 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, which were cyclized to the corresponding triazepines 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h on boiling with sodium ethoxide. Conversion of compound 1 to the methylthiocarbamate derivative 6 was performed through its reaction with carbon disulfide and KOH followed by treatment with methyl iodide. Compound 6 reacted with hydrazonoyl chlorides in presence of TEA to give thiadiazoles 8a, 8b, 8c, 8d, 8e, 8f, 8g. In addition, chromene 1 combined with aminodithiocarbamic acid in DMF under reflux to furnish the thiosemicarbazide derivative 9, which in turn interacted with several hydrazonoyl chlorides to give the thiazole derivatives 11a, 11b, 11c, 11d, 11e. The structures of the prepared compounds were confirmed from their spectroscopic data and elemental analysis. The synthesized compounds were tested against both monoamine oxidase (MAO)-A and MAO-B and corrected to analyses showed good inhibitory activities especially against MAO-A.

Thiazine Red(+) platelet inclusions in Cerebral Blood Vessels are first signs in an Alzheimer’s Disease mouse model

Strong evidence shows an association between cerebral vascular diseases and Alzheimer’s disease (AD). In order to study the interaction of beta-amyloid (A beta) plaques with brain vessels, we crossbred an AD mouse model (overexpressing amyloid precursor protein with the Swedish-Dutch-Iowa mutations, APP_SweDI) with mice expressing green fluorescent protein (GFP) under the flt-1/VEGFR1 promoter in vessels (GFP_FLT1). Our data show, that only very few A beta plaques were seen in 4-months old mice, focused in the mammillary body and in the lateral septal nucleus. The number of plaques markedly increased with age being most prominent in 12-months old mice. Thiazine Red was used to verify the plaques. Several Thiazine Red(+) inclusions were found in GFP(+) vessels, but only in non-perfused 4-months old mice. These inclusions were verified by Resorufin stainings possibly representing cerebral amyloid angiopathy. The inclusions were also seen in non-crossbred APP_SweDI but not in wildtype and GFP_FLT1 mice. In order to characterize these inclusions Flow Cytometry (FACS) analysis demonstrated that platelets were specifically stained by Thiazine Red(+), more pronounced when aggregated. In conclusion, our data show that Thiazine Red(+) inclusions representing aggregated platelets are a first pathological sign in AD before plaque development and may become important therapeutic targets in early AD.

Chemoselective Synthesis of Structurally Diverse 3,4-Dihydroquinazoline-2(1H)-thiones and 4H-Benzo[d][1,3]thiazines

An efficient, mild, and substrate/catalyst-controlled chemoselective reaction of o-isothiocyanato-(E)cinnamaldehyde with amines has been established, producing three types of six-membered heterocycles: 2-(4Hbenzo[d][1,3]thiazin-4-yl)acetaldehydes, 2-(2-thioxo-1,2,3,4-tetrahydroquinazolin-4-yl)acetaldehydes, and (E)-4-(2-methoxyvinyl)-4H-benzo[d] [1,3]thiazines. The reaction scopes were quite broad and excellent yield was achieved. This method is extremely efficient and practical and can be conducted on a gram-scale with slightly inferior reactivity under catalyst-free conditions at low cost, making it an ideal alternative to existing methods.

Discovery of an Extremely Potent Thiazine-Based beta-Secretase Inhibitor with Reduced Cardiovascular and Liver Toxicity at a Low Projected Human Dose

Genetic evidence points to deposition of amyloid-beta (A beta) as a causal factor for Alzheimer’s disease. A beta generation is initiated when beta-secretase (BACE1) cleaves the amyloid precursor protein. Starting with an oxazine lead 1, we describe the discovery of a thiazine-based BACE1 inhibitor 5 with robust A beta reduction in vivo at low concentrations, leading to a low projected human dose of 14 mg/day where 5 achieved sustained A beta reduction of 80% at trough level.
