NAD-based inhibitors with anticancer potential
Felczak, Krzysztof,Vince, Robert,Pankiewicz, Krzysztof W.
, p. 332 - 336 (2014)
Three classes of novel inhibitors of inosine monophosphate dehydrogenase have been prepared and their anti-proliferative properties were evaluated against several cancer cell lines. (1) Mycophenolic adenine dinucleotide analogues (8-13) containing a substituent at the C2 of adenine ring were found to be potent inhibitors of IMPDH (Ki's in range of 0.6-82 nM) and sub-μM inhibitors of leukemic K562 cell proliferation. (2) Mycophenolic adenosine (d and l) esters (20 and 21) showed a potent inhibition of IMPDH2 (Ki = 102 and Ki = 231 nM, respectively) and inhibition of K562 cell growth (IC50 = 0.5 and IC50 = 1.6 μM). These compounds serve both as inhibitors of the enzyme and as a depot form of mycophenolic acid. The corresponding amide analogue 22, also a potent inhibitor of IMPDH (Ki = 84 nM), did not inhibit cancer cell proliferation. (3) Mycophenolic-(l)-and (d)-valine adenine di-amide derivatives 25 (Ki = 9 nM) and 28 (Ki = 3 nM) were found to be very potent enzymatically, but did not inhibit proliferation of cancer cells.

Photocatalytic Alkylation of Pyrroles and Indoles with α-Diazo Esters

supporting information, p. 7028 - 7032 (2019/09/12)
This article describes the photoalkylation of electron-rich aromatic compounds with diazo esters. C-2-alkylated indoles and pyrroles are obtained with good yields even though the photocatalyst loading is as low as 0.075 mol %. For EWG-substituted substrates, the addition of a catalytic amount of N,N-dimethyl-4-methoxyaniline is required. Both EWG-EWG- and EWG-EDG-substituted diazo esters are suitable as alkylating agents. The reaction selectivity and mechanistic experiments suggest that carbenes/carbenoid intermediates are not involved in the reaction pathway.
