Ma, Huijun;Qian, Anran;Zheng, Yazhou;Meng, Xin;Wang, Ting;Zhang, Yinyong;Sun, Lulu;Zou, Feng;Zhao, Bomei;Zhang, Shuhua;Zhang, Dan;Yang, Yushe research published 《 Design, Synthesis, and Structure-Activity Relationship Studies of Bisamide Derivatives of Amphotericin B with Potent Efficacy and Low Toxicity》, the research content is summarized as follows. Amphotericin B (AMB, 1) is the most powerful antibiotic in treating potentially life-threatening invasive fungal infections (IFIs), though severe toxicity derived from self-aggregation greatly limits its clin. application. Herein, we applied a bisamidation strategy at the C16-COOH and C3′-NH2 to improve the therapeutic properties by suppressing self-aggregation. It was found that basic amino groups at the residue of C16 amide were beneficial to activity, while lipophilic fragments contributed to toxicity reduction Addnl., N-methyl-amino acetyl and amino acetyl moieties at C3′ amide could help keep the fungistatic effectiveness. The modification work culminated in the discovery of 36 (I) (ED50 = 0.21 mg/kg), which exerted a 1.5-fold stronger antifungal efficacy than amphamide, the optimal derivative theretofore, in mice, low self-aggregation propensity, and thus low acute toxicity. With the improvement in therapeutic index and good PK profile, 36 is promising for further development as a second-generation polyene antifungal agent.
Formula: C5H11NO, 4-Hydroxypiperidine is a molecule with a carbonyl group. It is the most active and selective CCR5 receptor antagonist that has been studied to date. 4-Hydroxypiperidine inhibits HIV infection by preventing the binding of HIV to its receptor on the surface of white blood cells, thereby preventing it from entering these cells. 4-Hydroxypiperidine also acts as an anti-inflammatory agent in chronic bronchitis patients, due to its ability to inhibit prostaglandin synthesis. The chemical ionization mass spectra of this molecule show peaks for methyl ethyl, malic acid, and hydroxyl groups. These properties make 4-hydroxypiperidine a useful candidate for drug development against inflammatory diseases and several cancers.
The molecular structure, vibrational spectra, NBO and UV-spectral analysis of 4-Hydroxypiperidine have been studied. The compounds with a substituted 4-piperidinol core have been found to be potent antagonists of the human H receptor., 5382-16-1.
