  The carbonate analogues of 5′-halogenated resiniferatoxin as TRPV1 ligands

  摘要：

  A series of carbonate analogues of 5'-halogenated RTX have been investigated in order to examine the effect of the carbonate group as a linker and the role of halogens in the reversal of activity from agonism to antagonism for rat and human TRPV1 heterologously expressed in Chinese hamster ovary cells. The carbonate analogues showed similar activities to the corresponding RTX derivatives in rat TRPV1 but lower potency in human TRPV1. 5-Halogenation converted the agonists to partial agonists or full antagonists and the extent of antagonism reflected the order of I > Br > Cl > F, with a somewhat greater extent of antagonism for the derivatives of the 4-amino RTX surrogates compared to the corresponding derivatives of RTX itself. The carbonate analogues of I-RTX: (60) and 5-bromo-4-amino-RTX (66) were potent and full antagonists with K-i(ant) = 2.23 and 2.46 nM, respectively, for rat TRPV1, which were ca. 5-fold more potent than I-RTX (2) under our conditions. The conformational analysis of the I-RTX-carbonate (60) indicated that its bent conformation was similar to that of I-RTX, consistent with compound 60 and I-RTX showing comparable potent antagonism.

  the benzofuro[3,2‐b]indoline framework could be obtained by PIDA‐mediated direct oxidative coupling of 2,3‐disubstituted‐indoles with phenols. Application of this chemistry allows for an eight‐step total synthesis of phalarine from commercially available tryptamine.

  我们首次报道，可通过PIDA介导的2,3-二取代吲哚与酚的直接氧化偶合获得苯并呋喃[3,2- b ]二氢吲哚骨架。该化学方法的应用使得可以从市售的色胺中进行八步法合成全草胺。
