Eliminative Ring Fission of 4-Acyl-2,3-dihydro-4H-1,4-benzothiazines

The behavior of 4-acyl-2,3-dihydro-1,4-benzothiazines 1-11 upon treatment with lithium diisopropylamide (LDA) in THF at -78 deg C has been examined.Very marked differences have been observed.Whereas unsubstituted and monosubstituted derivatives (1-4) readily undergo “eliminative ring fission”, providing 2-(alkylthio)phenylenamides 12, 2-aminophenyl vinyl sulfides 16, and 3-acylbenzothiazolines 13, 2,3-disubstituted derivatives (5-7) do not react at all.The relationship between structural features of the above-mentioned dihydrobenzothiazines and their reactivity is considered.Lithium ion plays a fundamental role in providing activation for the ring-opening reaction.

Photodynamic therapy in the treatment of periodontal diseases: A literature review

Aim: Periodontal diseases remain a challenging clinical condition and hence existing literature showed no consensus on the best treatment option for disease control. The aim of this review was to provide a comprehensive overview of exciting clinical evidence on the effect of photodynamic therapy (PDT) in the treatment of periodontal diseases. Materials and Method: A literature review was performed using MEDLINE, PubMed, Wiley, ScienceDirect, and Scopus using the terms PDT, periodontal disease, laser, scaling and root planning, chronic periodontitis, and aggressive periodontitis. Results: Of a total of 149 articles appeared from various sources, 147 articles were screened and 36 were related to the research objective. Adjunctive therapy with PDT may promote additional clinical and microbiological outcomes. Conclusion: Little information is available with regard to PDT photosensitizers, wavelength, number of sessions, and duration. Therefore, large randomized control trials with longer follow-up are needed to assess the potential of PDT in the treatment of periodontal disease.

Efficient and regioselective synthesis of phenothiazine via ferric citrate catalyzed C-S/C-N cross-coupling

Efficient C-S and C-N cross-coupling reactions have been developed for regioselective, scalable and environmentally benign synthesis of substituted phenothiazine derivatives. Cross-coupling reactions were demonstrated on various challenging substrates using non-toxic, highly economical, readily available ferric citrate as a catalyst to get desired product with high regioselectivity. Atom economy is the added advantage of this protocol since additional N-protection step before coupling and eventual deprotection of the same to obtain the desired product arenot required. To the best of our knowledge, this is the first report on the use of inexpensive ferric citrate as a catalyst without involving any ligand for the synthesis of regioselectively substituted phenothiazine.

6-Substituted and 5,6-disubstituted derivatives of uridine: Stereoselective synthesis, interaction with uridine phosphorylase, and in vitro antitumor activity

Stereoselective procedures are described for the synthesis of 6- alkyluridines by Lewis acid-catalyzed condensation of (a) trimethylsilylated 6-alkyl-4-alkylthiouracils with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D- ribofuranose (ABR) and (b) trimethylsilylated 6-alkyl-3-benzyluracils with ABR. The 4-methylthio group was subsequently removed with the use of 1 N trifluoroacetic acid and the 3-benzyl group by a new modified procedure with the use of the complex BBr3-THF. Furthermore, 6-(hydroxymethyl)uridine (39) and 5-fluoro-6-(hydroxymethyl)uridine (40) were obtained by sequential oxidation with SeO2 and reduction with tetrabutylammonium borohydride of the 6-methyl group of 6-methyluridine (5) and 5-fluoro-6-methyluridine (35), and their corresponding 6-fluoromethyl congeners 41 and 42 were obtained by DAST treatment of 39 and 40, respectively. For all the foregoing nucleosides in the fixed syn conformation about the glycosyl bond, 1H NMR spectroscopy further demonstrated that the pentose rings exist predominantly in the conformation N (3′-endo). Most of the nucleosides were weak substrates of Escherichia coli pyrimidine nucleoside phosphorylase. Enhanced susceptibility to phosphorolysis was exhibited by two of them, 39 and 41, with 6-CH2OH and 6-CH2F substituents capable of formation of an additional hydrogen bond with the enzyme. The 5-fluoro-6-substituted uridines were the poorest substrates. Cytotoxicities of the nucleosides were examined vs the human tumor cell lines MOLT-3, U-937, K-562, and IM-9, as well as PHA-stimulated human lymphocytes. Two of the analogues, 5-fluoro-6-(fluoromethyl)uridine (42) and 5-fluoro-6- (hydroxymethyl)uridine (40), exhibited cytotoxicities comparable to that of 5-fluorouracil.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about COA of Formula: C3H5NOS!, Computed Properties of C10H14N2O6S3
