The chromatographic parameters of arylpiperazinylpropyl derivatives of imidazolidine-2,4-dione and imidazo[2,1-f]purine-2,4-dione were investigated using reversed-phase thin layer chromatography method. The results revealed that R(M0) of investigated compounds depended on substituent in arylpiperazinyl fragment as well as on a nature of (cycloalkyl)aromatic ring at 5 position of imidazolidine-2,4-dione and at 7 position of imidazo[2,1-f]theophylline. The R(M0) parameters were compared with computationally calculated partition coefficients values by principal component analysis (PCA). To verify the influence of lipophilic parameter of investigated compounds on their biological activity the statistical analysis of Mann-Whitney was performed.

The current investigation intended to assess the controlled delivery of 7-sulfonamide-2-(4-methylphenyl) imidazo[2,1-b] [1, 3] benzothiazole an anticancer agent (ACA) by tamarind seed gum-based hydrogel; for its potential activity against hepatocellular carcinoma. The FTIR spectra, SEM, C NMR, PXRD, and TGA analyses evidenced the successful loading of ACA into the hydrogel system. The rheological testing conveyed the increase in the elastic nature of ACA-loaded hydrogel helping in an effective release.

In continuation of our efforts to develop new anticancer compounds, a new series of imidazo[1,5-]pyridine-chalcone derivatives was designed, synthesized, characterized, and evaluated for its cytotoxicity against five human cancer cell lines, , breast (MDA-MB-231), colon (RKO), bone (Mg-63), prostate (PC-3), and liver (HepG2) cell lines, as well as a normal cell line (HEK). Among the synthesized compounds, two exhibited promising cytotoxicity against the MDA-MB-231 cell line with IC values of 4.23 ± 0.

Two novel complexes, [Cu()Cl] and [Zn()Cl], were synthesized from 1,1'-[(3-fluoro-phen-yl)methyl-ene]bis-[3-(3-fluoro-phen-yl)imidazo[1,5-]pyridine] (), and copper(II) and zinc(II) chloride, respectively. The structures of these complexes were confirmed using ESI-MS, IR and H NMR spectra. The results reveal mononuclear structures in which the central metal atoms are coordinated by two N atoms from the imidazole rings and two Cl ligands.

Among the various cations, the Fe ion is one of the most critical transition metal ions in living cells for many cellular functions and enzymatic activities. The decrease or overloading of Fe can lead to different disruptions in humans. Also, Fe, highly toxic, is very common in all industrial wastewater.
