Ester cleavage by S,S-(+)-tetrandrine derivative bearing thiol groups
A chiral cyclophane–type macrocycle bearing two thiol groups has been prepared by chemical modification of S,S-(+)-tetrandrine. Cleavage of p-nitrophenyl acetate by deprotonated form of this macrocycle proceeds with a rate constant expected for a simple thiol anion of similar basicity, but the reactivity toward p-nitrophenyl esters of N-protected amino acids is one order of magnitude higher tha...
متن کاملThe free energy of thiol ester hydrolysis.
Thiol esters, such as aeetyl coenzyme A, the principal biological carrier of activated acetyl groups, have generally been supposed to be “energy-rich” compounds; i.e. to have a free energy of hydrolysis at pH 7.0 in the range of -7000 to -14,000 calories per mole. The reported numerical values for the free energy of thiol ester hydrolysis have varied over a wide range (for recent estimates see ...
متن کاملThiol-dependent DNA cleavage by aminomethylated Beaucage's reagent.
Aminomethylated Beaucage's reagent 1 was found to be more potent than 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage's reagent) in causing DNA cleavage. The current study demonstrated the importance of the amino functionality in enhancing DNA-cleaving activities, and such findings may facilitate development of novel sulfur-containing DNA-cleaving molecules in cancer therapy.
متن کاملPatients bearing gifts: are there strings attached?
semiformal dress may have introduced some bias. For example, the higher preferences for the semiformal nonsmiling doctor may have arisen by its association with a smile on another photograph. Ideally each dress style would have been presented with a smiling and non-smiling version, or the smiling option should have been randomly associated with any of the dress styles. Although these results ar...
متن کاملMetric groups attached to biextensions
Let G be a connected, unipotent, perfect group scheme over an algebraically closed field of characteristic p > 0 and let E be a biextension (cf. [SGA7tI], exp. VII, no. 1) of G ×k G by the discrete group Qp/Zp. When E is skewsymmetric (cf. sec. 3.1), V. Drinfeld defined in [Dr] a certain metric group A (cf. appendix) associated to E. In this article, we prove a conjecture stated in [Dr] (cf. se...
