Synthesis and antiproliferative assessments of new derivatives of isothiazolo[3,4-d]pyrimidine

Various derivatives of 5-aryl-4-imino-3-(phenylamino)-4,5-dihydroisothiazolo[3,4-d]pyrimidines (3a-f) were synthesized. The synthesis has been done through treatment of 3-amino-4-cyano-5-(phenylamino)isothiazole with various aryl isothiocyanates. The isothiazole skeleton was obtained by the reaction of malononitrile and phenyl isothiocyanate followed by chloramine treatment. Some of the synthesized dihydroisothiazolo[3,4-d]pyrimidines were tested against different cancer cell lines, including ACHN, HeLa, HL-60, MCF-7, and PC3. Malignant cells were cultured in RPMI medium and incubated with different concentrations of the mentioned compounds. Cell viability was assessed using the MTS assay. The cytotoxicities of the synthesized compounds are not significant and are probably safe for other biological use.

Crystallographic study of two monoazo disperse dyes with a D-pi-A system

Two azo disperse dyes, 2,6-dichoro-4-nitro-4,4-N-cyanoethyl-N-benzyl-azobenzene (D1) and 3-(3-methyl-4-N-ethyl-N-benzyl-phenyldiazenyl)-5-nitro-2,1-benzisothiazole (D2), were synthesised and characterised. The crystal morphologies and single crystal structures were measured. The various packing and supramolecular interactions were described. D1 formed stellate crystals. The two benzene rings bilateral to the azo unit were not coplanar. Their dihedral angle was 75.72 degrees. They were linked by the azo unit and were twisted. The coupling-component N-substituted benzyl and benzene rings were not coplanar. The chemical structure was not the typical azo structure. A dimeric packing mode was formed between adjacent molecules in a head-to-head and tail-to-tail manner. One molecule was inserted between two dimeric molecules in a head-to-tail manner. D2 formed globe crystals. The isothiazole and benzene rings of the azo unit were coplanar, with the typical – conjugated structure. The benzene rings of the azo unit and the coupling-component N-substituted benzyl were vertical. Their torsion angle was 179.9 degrees.

A theoretical study of the aromaticity of hypervalent sulfur heterocycles

In this paper we report on the heteroaromaticity of 1,2,5-thiadiazole-1,l-dioxide (I) and its isomers 1,2,4-thiadiazole-1,1-dioxide (II), 1,3,4-thiadiazole-1,I-dioxide (III) and 1,2,3-thiadiazoIe-1,1-dioxide (IV) by calculating their electronic structures and estimating their aromatic character in terms of our previously developed criteria: N, MDQ, Delta E-pi L(NLMO) and Delta E-pi L(Boys) as well as comparing their total energies. (I) is shown to be the most aromatic isomer in good agreement with chemical reasoning and experimental evidence. The 1,l-dioxides of thiazole and isothiazole were predicted to be intermediate in aromaticity between thiophene-l, 1-dioxide and the isomers, (I)-(N). N value measures indicate that thiophene-l,1-dioxide would retain a small measure of aromatic character relative to thiophene (N(thiophene) = 0.868, N(thiophene-l,l-dioxide) = 0.389).
