This is only the third example of a crystal structure containing a 2,1-benzisothiazole ring system. Bond lengths in the isothiazole ring of the title compound suggest much less double-bond character than observed in the other two known structures. The molecule is essentially planar and packs in the crystal with the benzisothiazole rings stacked in the [100] direction.

Anti-HIV evaluation of benzo[d]isothiazole hydrazones

The synthesis and the anti-HIV-1 activity of novel benzo[d]isothiazole hydrazones are reported. Target compounds tested in MT-4 cells cultures for their anti-HIV properties against wild type HIV-1 and HIV strains carrying clinically relevant mutations (EFV(R), Y181C and K103/Y181C) showed good activity against wild type HIV-1 and against the EFVR mutant. In terms of SAR the relevant result was that, in the class of benzisothiazole hydrazones, the benzo[d]isothiazol-3(2H)-one moiety (compounds 1 and 4) is an essential structural requirement for the anti-retroviral activity.

Single N-C Bond Becomes Shorter than a Formally Double N=C Bond in a Thiazete-1,1-dioxide Crystal: An Experimental and Theoretical Study of Strong Crystal Field Effects

3-Diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda(6),2-thiazete-4-carbonitrile (DTC) is a synthetic compound that exhibits a significant similarity with)beta-sultamic drugs. Its core chemical moiety is an uncommon four-membered thiazete-1,1-dioxide heterocycle. Former crystallographic investigations carried out at room temperature on different DTC polymorphs and a chemically related compound showed a very unusual structural feature: within the conjugated -N-C=N-SO2- system, the formally single N-C bond is, on average, 0.018 angstrom shorter than the formally double N=C bond. In this work, the charge density distribution of DTC has been explored by both single-crystal X-ray diffraction at T = 100(2) K and quantum mechanical simulations, with the aim of gaining insights into the subtle interplay between structure, electron delocalization, and crystal field polarization effects. To this end, both local and nonlocal topological descriptors provided by the Quantum Theory of Atoms in Molecules have been employed. Topological and structural changes of crystalline and in vacuo DTC have been related to the smaller or larger importance of resonance forms in the -N-C=N-SO2- moiety. A rationale for the mentioned C-N/C=N bond length inversion is found in terms of the large DTC dipole moment enhancement occurring in the crystal, which stabilizes highly polar resonant forms that exploit more favorable electrostatic interactions with neighboring molecules. In turn, this causes a significant electronic rearrangement within the molecule that results in an unusual and counterintuitive bond length alternation pattern. Possible implications from the viewpoint of the accurate in silico modeling of crystal structures are discussed.

HETEROCYCLIC HYDRAZONE DERIVATIVES AS INHIBITORS FOR ALUMINUM CORROSION IN HYDROCHLORIC-ACID SOLUTIONS

Corrosion rate of aluminium in 2N HCl solution in presence and absence of N-(o-hydroxybenzylidene)-2-amino-1,2,4-triazole, N-(o-hydroxybenzylidene)-5-amino-4-methyl isothiazole and N-(o-hydroxybenzylidene)-2-aminopyrazine (10(-3)-5 X 10(-6) Mol L-1) has been studied. Three different techniques, namely, weight loss, hydrogen evolution and thermometric have been used. The inhibition efficiencies of the different methods have been found in good agreement. The inhibition effect depends upon both the concentration and the character of the additives. The temperature effect has been studied, and it indicates that the inhibition process occurs through physical adsorption. The degree of surface coverage (O) of the adsorbed additives has been determined, the results obey the Langmuir adsorption isotherm. The effect of the chemical constitution on the order of corrosion efficiency of the studied compounds has also been explained.
