WebThe thioester, JTT-705 41a (Figure 15), is a prodrug for the thiol-based, covalent modifier, 41b, that irreversibly inhibits CETP.While 41b effectively inhibited CETP in human plasma (IC 50 =3 μM), it was too unstable for oral dosing and necessitated the identification of a suitable prodrug moiety. The iso-butyryl ester derivative 41a (IC 50 =6 μM) was nearly … WebThe thioester-containing proteins (TEPs) are accessory proteins of the complement system, homologous to proteins such as C3, C4, a2M and CD109s.

WebJul 20, 2024 · A thioester is more reactive than an ester, for example, because a thiolate (RS-) is a weaker base and better leaving group than an alcoxide (\(RO\)-). Recall from chapter 7 that the \(pK_a\) of a thiol is about 10, while the \(pK_a\) of an alcohol is 15 or higher: a stronger conjugate acid means a weaker conjugate base.

They are analogous to carboxylate esters (R−C(=O)−O−R’) with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix. They are the product of esterification of a carboxylic acid (R−C(=O)−O−H) with a thiol (R'−S−H). In biochemistry, the best-known thioesters are derivatives of coenzyme A, e.g., acetyl-CoA.
