Topically applied azaphenothiazines inhibit contact sensitivity to oxazolone in mice

In this work we investigated the efficacy of two topically applied azaphenothiazine derivatives, 9-chloro-6-acetylaminobutylquinobenzo[3,2-b][1,4]thiazine (compound 4) and 6-chloroethylureido-ethyldiquino[3,2-b;2′;3′-e][1,4]thiazine (compound 5), in the amelioration of inflammatory symptoms of contact sensitivity (CS) to oxazolone in mice, in relation to the commercial ointment Protopic (R) (tacrolimus), the reference drug. The compounds were administered 24 h following elicitation of CS and, 24 h later, the parameters of inflammation, such as ear edema, blood composition, leukocyte level, numbers of cells in the draining lymph nodes, histological picture of the inflamed tissue, and the morphometric analysis, were analyzed. The study showed that the effectiveness of the studied azaphenothiazines applied as a 0.1% ointment was comparable to the reference drug regarding suppression of the inflammatory process, when all the investigated histological parameters are taken into account.

A stereoselective thiocyanate conjugate addition to electron deficient alkynes and concomitant cyclization to N, S-heterocycles

A regio- and stereoselective thiocyanate addition to ynones is achieved using KSCN in AcOH at 70 degrees C. The reaction is extendable to ynals, ynesulfones, ynoic acids and ynoates. Adducts from ynones were readily transformed into thiazine-2-thione derivatives under slightly modified reaction conditions. In contrast, thiocyanated adducts from ynamides underwent an in situ decyanative amido cyclization towards isothiazolones. None of these events needed any transition metal or catalyst, attaining a high synthetic value.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 82911-69-1. The above is the message from the blog manager. COA of Formula: C19H15NO5.

Stereoselective Synthesis and Antiproliferative Activity of Monoterpene-Fused 2-Imino-1,3-oxazines

Background: In the recent years the 2-imino-1,3-thiazine and 2-iminothiazolidine ring systems can be found as moieties in biologically relevant compounds, including BACE1 inhibitors, or cannabinoid receptor agonists, while monoterpene-based 2-imino-1,3-thiazines, prepared from chiral 1,3-amino alcohols exhibiting pronounced antiproliferative activity. Methods: The antiproliferative activities of the prepared compounds were determined in vitro against a panel of human adherent cancer cell lines including HeLa, MCF7 and A431 by MTT assay. Results: Starting from pinane-, apopinane-and carane-based beta-amino acid derivatives, 1,3-amino alcohols were prepared via two-step syntheses. The reactions of the product 1,3-amino alcohols and aryl isothiocyanates yielded gamma-hydroxythioureas, which were transformed to monoterpene-fused 2-imino-1,3-oxazines via base-catalysed ring closure. The antiproliferative activities of these 2-imino-1,3-oxazines were examined and the structure-activity relationships were studied from the aspects of the type and stereochemistry of the monoterpene ring and the substituent effects on the 1,3-oxazine ring system. The N-unsubstituted monoterpene-based derivatives exhibited considerable antiproliferative activity against a panel of human adherent cancer cell lines (HeLa, MCF7 and A431). Conclusions: A mild and efficient method has been developed for the synthesis of 2-imino-1,3-oxazines by the ring closure of thiourea adducts of 1,3-amino alcohols. The resulting 1,3-oxazines exert marked antiproliferative action on a panel of human cancer cell lines.

Dipyrimido[4,5-b:5,4-e][1,4]thiazine: synthesis and their enzyme inhibitory activity assessment on soybean 15-lipoxygenase

A series of new derivatives of dipyrimido[4,5-b:5,4-e][1,4] thiazine were synthesized by treatment of 5-amino-6-methyl-2-morpholino-4-pyrimidinethiol (1) with 5-bromo-2,4-dichloro-6-methylpyrimidine (2) in the presence of triethylamine and ethanol and subsequently with various secondary amines in EtOH/DMF. The thioether derivative 3 and heterocyclization products 4a-f were characterized by elemental analysis and spectroscopic techniques. The 15-LO inhibitory activities of the new synthesized compounds were also evaluated. The results show that compound 4e has the best IC50 of 15-LO inhibition (IC50 = 14.4 A mu M) but when all the products were theoretically docked into 15-LO, the GOLD scores of compounds 4e and 4d are 43.67 and 43.39 respectively, which show the best results. We suggest that the hydrogen bond interaction between Ser489 of 15-LO and the nitrogen of piperazine ring of compound 4e appears to play major role in lipoxygenase inhibition.

Visible-light photocatalytic activation of N-chlorosuccinimide by organic dyes for the chlorination of arenes and heteroarenes

A variety of arenes and heteroarenes are chlorinated in moderate to excellent yields using N-chlorosuccinimide (NCS) under visible-light activated conditions. A screening of known organic dye photocatalysts resulted in the identification of methylene green as the most efficient catalyst to use with NCS. According to mechanistic studies described within, the reaction is speculated to proceed via a single electron oxidation of NCS utilizing methylene green under visible-light photoredox pathway. The photooxidation of NCS amplifies the electrophilicity of the chlorine atom of the NCS, thus leading to enhanced reactivity as a chlorinating reagent with aromatic substrates.

The role of S-bond in tenoxicam keto-enolic tautomerization

A non-steroidal anti-inflammatory drug, 4-hydroxy-2-methyl-N-2-pyridyl-2H-thieno.2,3-e)-1,2-thiazine-3-carboxamide 1,1-dioxide, called tenoxicam (TXM), with important implications in cancer treatment, has a peculiarity with respect to other molecules from the oxicam family. TXM is predominantly found in the zwitterionic form (ZWC) within the crystal structures of pure compounds and their solvates; however, it can be present in the beta-keto-enolic form (BKE) or beta-diketone (BDK) form. To understand this phenomenon, the combined effects of environment (solvent) and intra-molecular non-covalent interactions on the TXM keto-enol tautomerization were investigated through a combined experimental and computational study. We found that the polarity of a solvent had a minor influence on the crystallization process; this allowed to us synthesize and solve six new solvates with TXM in the ZWC form. Careful investigation of the non-covalent interactions between the sulphur atom of thiophenyl moiety and oxygen of the carbonyl group (S-bond) through a computational approach with the natural bond orbital (NBO) theory has shown that TXM crystallization is modulated by the S-bond. This study further confirms the importance of the S-bond in the drug design; however, nowadays, it is still underestimated.
