Gumus, Fatma published the artcileSynthesis, Cytotoxicity, and DNA Interactions of New Cisplatin Analogues Containing Substituted Benzimidazole Ligands, Computed Properties of 4760-35-4, the publication is Journal of Medicinal Chemistry (2009), 52(5), 1345-1357, database is CAplus and MEDLINE.

Six new platinum(II) complexes (I; R = CH₂Cl, CH₂OCOMe, CH₂CH₂OH; R₁ = H, Me) were synthesized and evaluated for their reactivity against model nucleophile I^–, cellular uptake, and in vitro antiproliferative activities against the human MCF-7 breast and HeLa cervix cancer cell lines. The effect of the compounds on pBR322 plasmid DNA was studied by gel electrophoretic mobility measurements. Flow cytometric anal. was also carried out to study the effect of representative compounds bearing 2-chloromethyl or acetoxymethylbenzimidazole substituents on the cell cycle distribution of MCF-7 and HeLa cells, resp. In general, it was found that Pt(II) complexes were less cytotoxic than cisplatin and were comparable to carboplatin. The results of the plasmid DNA interaction and the restriction studies suggest that changing the chem. structure of the benzimidazole ligands may modulate DNA binding mode and the sequence selectivity. The studied compounds had no significant effect on the cell cycle profile of the cells used. However, the acetoxymethylbenzimidazole derivative induced a significant increase in the SubG1 cell population at a concentration of 20 μM.

Accelerated stability studies of amaranth (FD & C Red No 2) [915-67-3] solution in the presence of some excipients commonly used in pharmaceutical formulations, namely, lactose [63-42-3], mannitol [69-65-8], syrup, gelatin, Tween 80 [9005-65-6], polyethylene glycol (PEG 6000, 4000 and 1500) [25322-68-3] and some drugs, namely, ascorbic acid [50-81-7], chlorpheniramine maleate [113-92-8], antazoline-HCl [2508-72-7], chlorpromazine-HCl [69-09-0] and diphenhydramine-HCl [147-24-0], were carried out at 60°. The dye solution itself was very stable. Lactose and mannitol did not produce marked effects on dye stability. Syrup and gelatin caused fading of the dye solution Complete discoloration of the dye solutions resulted in the presence of Tween 80, PEG 6000, 4000, and 1500 after storage of 12-48 h. Diphenhydramine-HCl, antazoline-HCl and chlorpheniramine maleate did not affect the stability of the dye. On the other hand, ascorbic acid caused fading of the dye solution within few hours. Chlorpromazine-HCl gave a faint pinkish violet colloidal solution when mixed with the dye solution

Kassem, A. A. published the artcileProlonged release antazoline hydrochloride tablets. Part 1. Using insoluble substances, Category: imidazoles-derivatives, the publication is Bulletin of the Faculty of Pharmacy (Cairo University) (1976), 14(1), 85-99, database is CAplus.

Addition of Mg stearate [557-04-0] and hydrogenated castor oil to antazoline-HCl (I) [2508-72-7] tablets made with Et cellulose [9004-57-3], prolonged the drug release. The tablets containing 15% and 20% Mg stearate released I more slowly in the gastric fluid than in the intestinal fluid, the release being more pronounced with the latter. Hydrogenated castor oil (10-20%) was perferred since it caused a gradual and uniform drug release both in gastric and intestinal fluids. Of the various retarding materials studied, hydrogenated castor oil caused the least erosion of I tablets, followed by Mg stearate.

Kassem, A. A. published the artcileProlonged release antazoline hydrochloride tablets. Part II. Using repeated granulation technique, Product Details of C17H20ClN3, the publication is Bulletin of the Faculty of Pharmacy (Cairo University) (1976), 14(1), 187-205, database is CAplus.

Repeated granulation of antazoline-HCl (I) [2508-72-7] with 5% and 10% Et cellulose [9004-57-3] and shellac solutions, followed by release-time study of the drug from its tablets, showed no increase in the release proportional to the concentration of the former binder. However, with shellac the increase in the release time was proportional to the concentration increase. In both cases, the release of I was relatively more rapid in gastric fluid than in that observed in intestinal fluid. The effects of number of granulations and surface area of the tablet on drug release were also studied. Shellac was more effective than Et cellulose in reducing the release of the drug.

Mowat, Jeffrey published the artcileIdentification of the Highly Active, Species Cross-Reactive Complex I Inhibitor BAY-179, Recommanded Product: 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is ACS Medicinal Chemistry Letters (2022), 13(3), 348-357, database is CAplus and MEDLINE.

Mitochondria are key regulators of energy supply and cell death. Generation of ATP within mitochondria occurs through oxidative phosphorylation (OXPHOS), a process which utilizes the four complexes (complex I-IV) of the electron transport chain and ATP synthase. Certain oncogenic mutations (e.g., LKB1 or mIDH) can further enhance the reliance of cancer cells on OXPHOS for their energetic requirements, rendering cells sensitive to complex I inhibition and highlighting the potential value of complex I as a therapeutic target. Herein, we describe the discovery of a potent, selective, and species cross-reactive complex I inhibitor. A high-throughput screen of the Bayer compound library followed by hit triaging and initial hit-to-lead activities led to a lead structure which was further optimized in a comprehensive lead optimization campaign. Focusing on balancing potency and metabolic stability, this program resulted in the identification of BAY-179, an excellent in vivo suitable tool with which to probe the biol. relevance of complex I inhibition in cancer indications.

White, Gemma V. published the artcileKallikrein 5 inhibitors identified through structure based drug design in search for a treatment for Netherton Syndrome, Product Details of C9H10N2O, the publication is Bioorganic & Medicinal Chemistry Letters (2019), 29(6), 821-825, database is CAplus and MEDLINE.

Netherton syndrome (NS) is a rare and debilitating severe autosomal recessive genetic skin disease with high mortality rates particularly in neonates. NS is caused by loss-of-function SPINK5 mutations leading to unregulated kallikrein 5 (KLK5) and kallikrein 7 (KLK7) activity. Furthermore, KLK5 inhibition has been proposed as a potential therapeutic treatment for NS. Identification of potent and selective KLK5 inhibitors would enable further exploration of the disease biol. and could ultimately lead to a treatment for NS. This publication describes how fragmentation of known trypsin-like serine protease (TLSP) inhibitors resulted in the identification of a series of phenolic amidine-based KLK5 inhibitors 1. X-ray crystallog. was used to find alternatives to the phenol interaction leading to identification of carbonyl analogs such as lactam 13 and benzimidazole 15. These reversible inhibitors, with selectivity over KLK1 (10-100 fold), provided novel starting points for the guided growth towards suitable tool mols. for the exploration of KLK5 biol.
