Role of sulphur-heterocycles in medicinal chemistry: An update

From many decades, S-heterocycles have maintained their status as an important part and core of FDA approved drugs and medicinally active compounds. With exhaustive exploration of nitrogen heterocycles in medicinal chemistry, researchers have shifted their interest towards other heterocycles, especially, S-heterocycles. Thus several attempts have been made to synthesize a variety of new sulphur containing compounds with high medicinal value and low toxicity profile, in comparison to previous N-heterocycles. Till today, S-heterocycle containing compounds have been largely reported as anticancer, antidiabetic, antimicrobial, antihypertension, antivral, antinflammatory etc. In this review, the authors have tried to provide a critical analysis of synthesis and medicinal attributes of sulphur containing heterocycles such as thiirane, thiophene, thiazole, thiopyran, thiazolidine etc reported within last five years to emphasize the significance and usefulness of these S-heterocycles in the drug discovery process.

Palladium(II) benzisothiazolinate (bit) complexes with amino-, acetylamino-, heterocyclic and phosphine co-ligands. Crystal structure of [Pd(bit)2(kappa2-dppe)]¡¤2EtOH

Abstract A series of square-planar palladium(II) benzisothiazolinate (bit) of the general type [Pd(bit)2L2] have been prepared and characterized by analytical and spectroscopic methods. Two synthetic routes have been employed, namely reactions of [Pd(bit)2]¡¤H2O with two equivalents of ligands (L = amine, amide, phosphine) or nucleophile displacement of chloride by benzisothiazolinate starting from trans-[PdCl2L2]. Both routes afford the new complexes in good yields as easily isolated, air and moisture stable, colored solids. The precursor, [Pd(bit)2]¡¤H2O, is itself prepared in high yields upon reaction of Na[bit] with Na2[PdCl4] in methanol and the analogous platinum complex, [Pt(bit)2]¡¤H2O, is similarly prepared from K2[PtCl4]. It is not clear if these species are mono- or dimeric, and formulation as [M2(mu-bit)4(H2O)2] with the four benzisothiazolinate spanning the metal-metal vector and possibly binding through coordination of nitrogen and oxygen is suggested. Diphosphine adducts, cis-[Pd(bit)2{kappa2-Ph2P(CH2)nPPh2}] (n = 1-4) can be prepared both upon addition of the diphosphine to [Pd(bit)2]¡¤H2O and from reactions of cis-[PdCl2{kappa2-Ph2P(CH2)nPPh2}] with two equivalents of Na[bit]. A crystal structure of cis-[Pd(bit)2(kappa2-dppe)] reveals that the benzisothiazolinate ligands are bonded in a monodentate fashion through nitrogen and this binding mode is proposed for all [Pd(bit)2L2] and [Pd(bit)2L] complexes. With dppb (n = 4) a second product is seen by NMR spectroscopy being proposed to be the part-substituted complex cis-[PdCl(bit)(kappa2-dppb)], while with dppm (n = 1) two further products are seen spectroscopically, proposed as trans-[Pd(bit)2(kappa1-dppm)2] and (more tenuously) [Pd2(bit)4(dppm)2]. The former is also prepared in good yields from reaction of [Pd(kappa2-dppm)2]Cl2 with Na[bit]. These studies show that palladium benzisothiazolinate are easily accessed and show good air and moisture stability.

Gas phase basicities of polyfunctional molecules. Part 6: Cyanides and isocyanides

This paper gathers structural and thermochemical informations related to the gas-phase basicity of molecules containing cyanides (nitriles) and isocyanides (isonitriles) functional groups. It constitutes the sixth part of a general review devoted to gas-phase basicities of polyfunctional compounds. A large corpus of cyanides and isocyanides molecules is examined under seven major chapters. In the first one, a rapid overview of the definitions and methods leading to gas-phase basicity, GB, proton affinity, PA, and protonation entropy, DeltapS, is given. In the same chapter, several aspects of the gas phase chemistry of protonated cyanides and isocyanides are also presented. Chapters II-VI detail the protonation energetics of aliphatic, unsaturated, and heteroatom substituted (halogens, O, S, N, P) cyanides. A seventh chapter is devoted to isocyanides. Experimental data available in the literature (120 references) were reevaluated according to the presently adopted basicity scale that is the NIST database anchored to PA(NH3) = 853.6 kJ/mol and GB (NH3) = 819 kJ/mol. In this latter source, however, several erroneous values have been identified which were corrected in the present review. Structural and energetic information given by G4MP2 quantum chemistry computations on ca. 60 typical systems are presented. The present review includes the GB, PA, and DeltapS values of ca. 110 cyanides and isocyanides, and, for selected examples, is completed by a set of computed heats of formation (DeltafH) at 0 and 298 K.

Synthesis and biological activity of novel comenic acid derivatives containing isoxazole and isothiazole moieties

Methyl 5-hydroxy-4-oxo-4H-pyran-2-carboxylate was synthesized by esterification of methanol with comenic acid under acidic catalysis. The obtained ester was alkylated with 3-(chloromethyl)-5-phenylisoxazole and 4,5-dichloro-3-(chloromethyl)isothiazole to afford corresponding conjugates containing isoxazole and isothiazole moieties which then were transformed into water-soluble Li-salts. During the bioassays of synthesized isoxazole and isothiazole derivatives of comenic acid in mixtures with first-line antitumor drug Temobel (Temozolomid) used in brain tumors chemotherapy, a synergetic effect was observed.
