ABSTRACT: The condensation of various thiosemicarbazones with methyl thiophene-2-carboximidate afforded the corresponding intermediates 2a–2h. Subsequent cyclization of the latter compounds with hexamethylphosphorous triamide constitutes a new route to the synthesis of novel highly functionalized thiadiazaphosphole derivatives 4a–4h. This method offers significant advantages such as efficiency, high yields and mild reaction conditions.

Paragraph 0011; 0040-0043, (2020/03/06)
The invention discloses a copper compound taking 2-thiophenecarboxaldehyde thiosemicarbazone as a ligand and a synthesis method of the copper compound. The synthesis method comprises the following steps: adding thiosemicarbazone into absolute ethyl alcohol, performing stirring and dissolution, adding 2-thiophenecarboxaldehyde, performing uniform mixing, stirring the mixed solution at 70 DEG C in awater bath, performing volatilization at room temperature, separating a crystal so as to obtain a ligand; and adding the prepared ligand into absolute ethyl alcohol, performing stirring and dissolving, adding CuBr2.2H2O after dissolution, performing stirring at 70 DEG C in a water bath, performing volatilization at room temperature, and separating out a crystal, so as to obtain a Cu compound of the ligand. An in-vitro proliferation inhibition activity experiment is further carried out on the synthesized copper compound, results show that the synthesized series of copper compounds have generally good in-vitro activity, particularly have high specificity on human T24 and HeLa cells, show good inhibitory activity, have little toxic effect on human normal cells, and are suitable for preparingefficient and low-toxicity anti-tumor drugs.

A series of thiosemicarbazones and their platinum(II) and palladium(II) complexes have been synthesized. The chemical structures of ligands and their complexes were characterized by UV-Vis, IR, 1H NMR, 13C NMR, MS spectra, elemental analysis and TGA. The antiviral and cytotoxic activities of all compounds have been tested. Results of broad antiviral evaluation showed that none of the compounds evaluated endowed with anti-DNA or -RNA virus activity at subtoxic concentrations except for the palladium complex 1b. This compound exhibited slightly selective inhibition against cytomegalovirus. The platinum complex 4a exhibited the best cytostatic activities against human cervix carcinoma. Ligands 2, 4 and 5 showed cytostatic potential. The palladium complexes were in general less cytostatic than the corresponding platinum complexes or unliganded congeners.

Ribonucleotide reductase (RR) is an important therapeutic target for anticancer drugs. The structure of human RR features a 1:1 complex of two homodimeric subunits, hRRM1 and hRRM2. Prokaryotically expressed and highly purified recombinant human RR subunits, hRRM1 and hRRM2, were used for holoenzyme-based [3H]CDP reduction in vitro assay. Ten new thiosemicarbazones (7-16) were synthesized and screened for their RR inhibitory activity. Two thiosemicarbazones derived from p-hydroxy benzaldehyde (9 and 10) were found to be active but less potent than the standard, Hydroxyurea (HU). Guided by the activity of compounds 9 and 10, 11 new thiosemicarbazones (17-27) derived from p-hydroxy benzaldehyde were prepared and screened for their RR inhibitory activity. All the 11 compounds were more potent than HU.
