Abstract
Synthetic methods for unsymmetrical aminodisulfides are greatly needed due to their applications in drug discovery, linker chemistry, and materials sciences. In this study, an amination reaction of N-dithiophthalimides has been developed for the divergent synthesis of unsymmetrical aminodisulfides. The reaction proceeds under mild conditions and provides the aminodisulfides in excellent yields without cleavage of the disulfide bond. The N-dithiophthalimides are readily available from several bilateral disulfurating reagents, and the broad substrate scope of this reaction allows for the modular synthesis of a variety of unsymmetrical aminodisulfides in two-step operations.

Crystal Structure and Solid-State Packing of 4-Chloro-5 H-1,2,3-dithiazol-5-one and 4-Chloro-5 H-1,2,3-dithiazole-5-thione. Molecules 2021; 26:molecules26195875.

Abstract
The crystal structure and solid-state packing of 4-chloro-5H-1,2,3-dithiazol-5-one and two polymorphs of 4-chloro-5H-1,2,3-dithiazole-5-thione were analyzed and compared to structural data of similar systems. These five-membered S,N-rich heterocycles are planar with considerable bond localization. All three structures demonstrate tight solid-state packing without voids which is attributed to a rich network of short intermolecular electrostatic contacts. These include Sδ+…Nδ−, Sδ+…Oδ−, Sδ+…Clδ− and Sδ+…Sδ− interactions that are well within the sum of their van der Waals radii (∑VDW). B3LYP, BLYP, M06, mPW1PW, PBE and MP2 were employed to calculate their intramolecular geometrical parameters, the Fukui condensed functions to probe their reactivity, the bond order, Bird Index and NICS(1) to establish their aromaticity.

Abstract
Heteroatom rich 1,2,3-dithiazoles are relatively underexplored in medicinal chemistry. We now report screening data on a series of structurally diverse 1,2,3-dithiazoles and electronically related 1,2,4-dithiazines with the aim of identifying interesting starting points for potential future optimisation. The 1,2,3-dithiazoles, were obtained via a number of different syntheses and screened on a series of cancer cell lines. These included breast, bladder, prostate, pancreatic, chordoma and lung cancer cell lines with an additional skin fibroblast cell line as a toxicity control. Several low single digit micromolar compounds with promising therapeutic windows were identified for breast, bladder and prostate cancer. Furthermore, key structural features of 1,2,3-dithiazoles are discussed, that show encouraging scope for future refinement.

Abstract
A new synthetic pathway to four substituted imidazoles from readily available 2-((4-aryl(thienyl)-5H-1,2,3-dithiazol-5-ylidene)amino)phenols has been developed. Benzo[d]oxazol-2-yl(aryl(thienyl))methanimines were proved as key intermediates in their synthesis. The formation of an imidazole ring from two methanimine derivatives likely includes the opening of one benzoxazole ring followed by ring closure by intermolecular nucleophilic attack of the N-methanimine atom to a carbon atom of another methanimine.

Abstract
Thermolysis of 4,4'-dichloro-, 4,4'-diaryl-, and 4,4'-di(thien-2-yl)-5,5'-bi(1,2,3-dithiazol-ylidenes) affords the respective 3,6-dichloro-, 3,6-diaryl- and 3,6-di(thien-2-yl)isothiazolo[5,4-d]-isothiazoles in low to high yields. The transformation of the 4,4'-diaryl- and 4,4'-di(thien-2-yl)-5,5'-bi(1,2,3-dithiazolylidenes) occurs at lower temperatures in the presence of the thiophiles triphenylphosphine or tetraethylammonium iodide. Optimized reaction conditions and a mechanistic rationale for the thiophile-mediated ring transformation are presented.

Abstract
A benzopentasulfane was synthesized in 8 steps with a ceramide attached through an amide bond to the 7-position of the heterocycle structure. The anticancer activity of this synthetic ceramide-benzopolysulfane drug conjugate was analyzed against five human cancer cell lines MDA-MB-231 (breast), DU145 (prostate), MIA PaCa-2 (pancreas), HeLa (cervix), and U251 (glioblastoma). The ceramide-benzopolysulfane conjugate had IC50 values ranging from 10 to >20 μM with complete cell killing at 12.5 μM for MDA-MB-231 and 20 μM for DU145 and HeLa cells. The ceramide-benzopolysulfane conjugate had IC50 values 1.8 and 4.0 times lower than a PEG benzopolysulfane, N-(2-(2-(2-methoxyethoxy)ethoxy)ethyl)benzo[f][1,2,3,4,5]-pentathiepine-7-carboxamide, for MDA-MB-231 and DU145 cells, respectively. The parent "unsubstituted" benzopolysulfane, o-C6H4S5, had IC50 values 4.2 times lower and 2.7 times higher than the ceramide benzopolysulfane for MDA-MB-231 and DU145 cells, respectively. The results indicate that the polysulfur linkage is needed for activity since benzenedithiol, o-C6H4(SH)2, had IC50 values greater than 30 μM with little effect on MDA-MB-231 and DU145 cells. Thus, to account for the bioactivity, a bimolecular reaction of cellular thiol with the ceramide benzopolysulfane is a proposed followed by thiozone (S3) extrusion.
