Piperidine the name comes from the genus name Piper, which is the Latin word for pepper. 5382-16-1, formula is C5H11NO, Name is 4-Piperidinol. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring solenopsins. Reference of 5382-16-1.
Zhu, Peiyu;Zhang, Jian;Yang, Yifei;Wang, Lixun;Zhou, Jinpei;Zhang, Huibin research published 《 Design, synthesis and biological evaluation of isoxazole-containing biphenyl derivatives as small-molecule inhibitors targeting the programmed cell death-1/ programmed cell death-ligand 1 immune checkpoint》, the research content is summarized as follows. Monoclonal antibodies targeting the programmed cell death-1/ programmed cell death-ligand 1 (PD-1/PD-L1) immune checkpoint have achieved enormous success in cancer immunotherapy. But the antibody-based immunotherapies carry a number of unavoidable deficiencies such as poor pharmacokinetic properties and immunogenicity. Small-mol. PD-1/PD-L1 inhibitors offer the superiority of complementarity with monoclonal antibodies and represent an appealing alternative. A novel series of isoxazole-containing biphenyl compounds were designed, synthesized and evaluated as PD-1/PD-L1 inhibitors in this paper. The structure-activity relationship of the novel synthesized compounds indicated that the ring-closure strategy of introducing isoxazole could be employed and the 3-cyanobenzyl group was significant for the inhibitory activity against the PD-1/PD-L1 protein-protein interactions. Mol. docking studies were performed to help understand the binding mode of the small-mol. inhibitor with the PD-L1 dimer. In particular, compound II-12 was a promising anti-PD-1/PD-L1 inhibitor with the IC50 value of 23.0 nM, providing valuable information for future drug development.
5382-16-1, 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., Reference of 5382-16-1
