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.

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 82911-69-1 help many people in the next few years. Quality Control of N-(9-Fluorenylmethoxycarbonyloxy)succinimide.

Site-Selective Pd-Catalysed Fujiwara-Moritani type Reaction of N,S-Heterocyclic Systems with Olefins

Dihydro-1,4-thiazine skeletons bearing olefin fragment at their alpha-position were prepared through a Pd(OAc)(2)-catalysed Fujiwara-Moritani type reaction via C-H alkenylation with olefins. This approach is selective, generalizable to a wide range of olefins and requires only 1 eq. of Ag2CO3 without the need of co-oxidant. The C-H bond activation proved to be strongly dependent on the olefin’s substitution while unfused dihydro-1,4-thiazines seemed to be affected by the oxidation state of the sulfur atom. The utility of olefins obtained was demonstrated by their implication in the dipolar cycloaddition reaction with a non-stabilized azomethine ylide.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 110553-27-0. Safety of 2-Methyl-4,6-bis((octylthio)methyl)phenol.

Facile synthesis of some condensed 1,3-thiazines and thiazoles under conventional conditions: antitumor activity

1,3-Thiazine 3 was obtained from cinnamoyl thiourea derivative 2 as the kinetic control product. Refluxing of 2 with sodium ethoxide afforded pyrimidine derivative 4. Moreover, stirring of 2 with bromine/acetic acid gave thiazole 5 that was condensed with o-phenylene diamine forming benzimidazole 6. Heating of arylthiourea 8 with maleic anhydride or phenacyl chloride afforded thiazole derivatives 9 and 10, respectively. Condensation of compound 10 with o-phenylene diamine gave benzimidazole 11. Reaction of p-amino benzoic acid with chloro acetyl isothiocyanate, acetylacetone and ethylacetoacetate produced imidazole 14, enaminone 15 and crotonate 16 derivatives, respectively. Stirring a mixture of benzoyl isothiocyanate with 15 and/or 16 resulted in pyridine-2-thione 17. The yields of the prepared compounds were 41-93%. The experimental section is simple and easy. The detailed synthesis, spectroscopic data, IC50 and antitumor activity of the synthesized compounds were reported. The cytotoxicity of the newly synthesized products showed that compound 4 is the most active compound towards the cancer cell line at which its reactivity is higher than that of the standard doxorubicin (anticancer reference drug).

Synthesis, reactions, and antimicrobial evaluations of new benzo[e][1,3]thiazine derivatives

4H-Spiro[benzo[d][1,3]oxathiine-2,1 ‘-cyclohexan]-4-one undergoes aminolysis with certain aromatic amines to give the respective 4-benzenesulfonamide, Ethyl benzoate, and 4-acetylphenyl of 4-oxospirobenzo[e][1,3]thiazine derivatives. The Schiff bases prepared by reacting Ethyl benzoate derivative 2a with aldehydes, undergoes cyclocondensation with thioglycolic acid yielding p-methoxyphenyl and 2-(thiophen-2-yl) thiazolidinone derivatives. Treatment of the benzoate derivative with hydrazine hydrate afforded the corresponding benzohydrazide derivative which upon reaction with phenyl isocyanate and phenyl isothiocyanate afforded the urea and thiourea derivatives. New pyrimidine, pyridone, and imino pyridine derivatives of 4-oxospirobenzo[e][1,3]thiazine were also successfully prepared by reacting 2b or 2c with the appropriate organic reagents. Structural elucidations for the new products were based upon compatible microanalytical and spectroscopic measurements. Besides, their biological screening indicated that they possess potent antimicrobial activity in comparison with reference drugs.

Synthesis of Pyrazine-1,3-thiazine Hybrid Analogues as Antiviral Agent Against HIV-1, Influenza A (H1N1), Enterovirus 71 (EV71), and Coxsackievirus B3 (CVB3)

A novel series of pyrazine-1,3-thiazine hybrid conjugates were synthesized in excellent yield. These derivatives were subsequently tested against human immunodeficiency virus (HIV-1); hemagglutinin type 1 and neuraminidase type 1’influenza’ A (H1N1) virus; enterovirus 71 (EV71); and coxsackievirus B3. The effect of these conjugates on the key enzymes responsible for the progression of these viral infections was also illustrated via enzyme-based assay, such as HIV-1 reverse transcriptase (RT) and neuraminidase, where entire tested molecules showed considerable inhibition. Particularly, among the tested derivatives, compound 3k was identified as most promising inhibitor of HIV-1 with 94% of inhibition (IC50 3.26 +/- 0.2 m). Moreover, the compound 3d was found to be the most potent analogue to inhibit the H1N1 virus with IC50 of 5.32 +/- 0.4 m together with inhibition of the neuraminidase enzyme (IC50 11.24 +/- 1.1 m). In regard to inhibitory activity against enterovirus 71 (EV71) and coxsackievirus B3 (CVB3), the tested derivatives showed considerable inhibition of infection. Molecular docking studies were also performed for the most promising inhibitors with their corresponding target protein to exemplify the structural requirement for better inhibitory activity. The results of inhibitory assay showed that designed molecules possess considerable inhibitory activity against the virus tested.

Synthesis, characterization and antimicrobial activity of new chalcones and their 6-aryl-4-(2,5-dichlorothiophen-3-yl)-6H-1,3-thiazin-2-amine derivatives

Chalcones (5a-h) were prepared in high yields via the condensation of 3-acetyl-2,5-dichlorothiophene (3) with aryl aldehydes (4a-h). The reaction of the resulting chalcones with thiourea in the presence of a catalytic amount of hydrochloric acid provided the 1,3-thiazin-2-amine derivatives (6a-g) in moderate yields. All new compounds were characterized by extensive NMR analysis data, including 1D NMR experiments (H-1 and C-13) and 2D NMR experiments (COSY, HMBC, HSQC), as well as ESIMS and HRESIMS data. The newly synthesized compounds were evaluated for their biological activities, which demonstrate a very good to low bioactivities as antibacterial and antifungal, respectively. [GRAPHICS] .

Internal heavy atom effects in phenothiazinium dyes: enhancement of intersystem crossing via vibronic spin-orbit coupling

The effect of substituting the intra-cyclic sulphur of thionine by oxygen (oxonine) and selenium (selenine) on the intersystem crossing (ISC) efficiency has been studied using high level quantum mechanical methods. The ISC rate constants are considerably increased when going from O towards Se while the fluorescence rate constants remain unchanged. For the three dyes, all accessible ISC channels are driven by vibronic spin-orbit coupling (SOC) between pi pi* states. The interplay between the ground and low-lying excited states has been investigated in order to determine the dominant relaxation pathways. In oxonine the relaxation to the ground state after photoexcitation in water proceeds essentially via fluorescence from the S-1(pi(H)pi(L)*) bright state (k(F) = 2.10 x 10(8) s(-1)), in agreement with the high experimental fluorescence quantum yield. In aqueous solution of thionine, the ISC rate constant (k(ISC) similar to 1 x 10(9) s(-1)) is one order of magnitude higher than fluorescence (k(F) = 1.66 x 10(8) s(-1)) which is consistent with its high triplet quantum yield observed in water (phi(T) = 0.53). Due to a stronger vibronic SOC in selenine, the ISC rate is very high (k(ISC) similar to 10(10) s(-1)) and much faster than fluorescence (k(F) = 1.59 x 10(8) s(-1)). This suggests selenine-based dyes as very efficient triplet photosensitizers.
