In studying CO pharmacology, dose dependency has not been properly studied in most, if not all, such work. Part of the reason is the difficulty in determining the solution concentration of a gaseous molecule (CO) with limited water solubility (~1 mM). Along this line, CO solution prepared at a pre-determined concentration has been widely used in studying CO pharmacology. However, different from making a solution of a non-volatile small-molecule drug, CO is expected to quickly escape from the solution, leading to unknown concentrations and an intractable scenario for dose-dependency studies. In this study, we hope to help define the boundary conditions by studying the concentration decay profiles of CO in solution at a pre-determined concentration. Results from such studies will be very important foundational information for future dose-dependency studies of CO pharmacology.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":699,"journal":{"name":"Medicinal Chemistry Research","volume":"34 5","pages":"1136 - 1143"},"PeriodicalIF":2.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of halogens was notably cytotoxicity against cells, but the bromo-substituted compound <b>6c</b> was further analyzed under five-dose screening at different concentrations, including 10⁻⁴, 10⁻⁶, 10⁻⁵, 10⁻⁷, and 10⁻⁸M. It was concluded that EKVX and UACC-257 cell lines were shown to be −6.58 (lowest) and −4.65 (highest) GI₅₀ at log₁₀ high concentration −4.0, respectively. However, TGI values for RXF and UACC-257 cell lines were shown to be −5.12 (lowest) and −4.0 (more than) at the same concentrations. The lowest LC₅₀ value was calculated at −4.50 for RXF 393 cell line, while the highest LC₅₀ value was noted at less than −4.0 for the T-47D cell of breast cancer at log₁₀ high concentration −4.0, respectively. The aim of research is to demonstrate the halogen’s effects on human cancer cells whenever it is attached at a suitable position at C-5 of the oxindole ring.

Key findings demonstrated that in the benzimidazole series, both aromatic rings and hydroxyl groups are essential for activity, as removal of the substituted benzyl ring and variations in the phenyl ring substituents led to a complete loss of activity, highlighting the importance of both aromatic rings and the hydroxyl groups, confirmed by docking studies showing crucial interactions of these groups with the Glo-I active site.
