  Kinetics of Reactions of Cyclopropylcarbinyl Radicals and Alkoxycarbonyl Radicals Containing Stabilizing Substituents: Implications for Their Use as Radical Clocks

  摘要：

  The rate constants for rearrangement of alpha-substituted cyclopropylcarbinyl radicals have been measured by nitroxide radical-trapping (NPT). Those bearing methyl, dimethyl, or cyclopropyl substituents undergo ring opening 2-3 times more slowly than does cyclopropylmethyl radical, but the reaction is essentially irreversible under the conditions used. Phenyl and tert-butoxycarbonyl alpha-substituents retard the rate of ring opening more strongly and enhance the rate of ring closure of the corresponding substituted but-3-enyl radicals. Thus for c-C(3)H(5)CHPh at 60 degrees C, k(ring open) = 5.4 x 10(5) s(-1), k(ring close) = 1.5 x 10(7) s(-1), and the equilibrium favors the ring closed form (K-equil = 0.04). The implications of the possible reversibility of the ring opening of substituted cyclopropylcarbinyl radicals for cyclopropane probe studies of metal hydride reduction and other chemical/biochemical reactions are assessed. Most of the cyclopropylcarbinyl radicals were generated from tert-butyl peroxyglyoxaletes (ROC(O)CO(3)Bu(t)) via alkoxycarbonyl radicals (ROCO). This method allowed the determination of the rate constants for decarboxylation of ROCO when R is t-Bu, PhCH(2), c-C(3)H(5)CMe(2), c-C(3)H(5)CHMe, (c-C3H5)(2)CH, or c-C3H5CHC6H(5).

  Compounds, methods of use, and processes for making inhibitors of complement factor D comprising Formula I, or a pharmaceutically acceptable salt or composition thereof, wherein R 12 or R 13 on the A group is a carbamate, ester, or ketone substituent (R 32 ) are provided. The inhibitors described herein target factor D and inhibit or regulate the complement cascade at an early and essential point in the alternative complement pathway, and reduce factor D's ability to modulate the classical and lectin complement pathways. The inhibitors of factor D described herein are capable of reducing the excessive activation of complement, which has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer.
