  A Novel Agonist of the Type 1 Lysophosphatidic Acid Receptor (LPA₁), UCM-05194, Shows Efficacy in Neuropathic Pain Amelioration

  摘要：

  Neuropathic pain (NP) is a complex chronic pain state with a prevalence of almost 10% in the general population. Pharmacological options for NP are limited and weakly effective, so there is a need to develop more efficacious NP attenuating drugs. Activation of the type 1 lysophosphatidic acid (LPA(1)) receptor is a crucial factor in the initiation of NP. Hence, it is conceivable that a functional antagonism strategy could lead to NP mitigation. Here we describe a new series of LPA(1) agonists among which derivative (S)-17 (UCM-05194) stands out as the most potent and selective LPA(1) receptor agonist described so far (E-max = 118%, EC50 = 0.24 mu M, KD = 19.6 nM; inactive at autotaxin and LPA(2-6) receptors). This compound induces characteristic LPA(1)-mediated cellular effects and prompts the internalization of the receptor leading to its functional inactivation in primary sensory neurons and to an efficacious attenuation of the pain perception in an in vivo model of NP.

• Facile and selective deprotection of PMB ethers and esters using oxalyl chloride
  作者：Andivelu Ilangovan、Karnambaram Anandhan、Mahabir Prasad Kaushik

  DOI：10.1016/j.tetlet.2015.01.061

  日期：2015.2

  Oxalyl chloride, (0.5 equiv) was found to cleave the PMB group from alkyl, aryl PMB ethers, and esters to give corresponding alcohol and acid in good yields. This method offers simple and efficient protocol for the selective deprotection of PMB ether and ester in DCE at ambient temperature.

  发现草酰氯（0.5当量）可将PMB基团从烷基，芳基PMB醚和酯中裂解出来，从而以高收率得到相应的醇和酸。该方法为环境温度下DCE中PMB醚和酯的选择性脱保护提供了简单有效的方案。
