Synthesis and in vitro antimalarial testing of neocryptolepines: SAR study for improved activity by introduction and modifications of side chains at C2 and C11 on indolo[2,3-b]quinolines

To obtain a high antimalarial activity with neocryptolepine derivatives, modifying and changing the side chains at the C11 position with varying the substituents of an electron-withdrawing or electron-donating nature at the C2 position for a SAR study were executed. Installation of alkylamino and omega-aminoalkylamino groups at the C11 position of the neocryptolepine core was successful. For further variation, the aminoalkylamino substituents were transformed into the corresponding acyclic or cyclic carbamides or thiocarbamides. These side chain modified neocryptolepine derivatives were tested for antimalarial activity against CQR (K1) and CQS (NF54) of Plasmodium falciparum in vitro and for cytotoxicity toward mammalian L6 cells. Among the tested compounds, the compound 17f showed an IC50 of 2.2 nM for CQS (NF54) and a selectivity index of 1400, and 17i showed an IC50 of 2.2 nM for CQR (K1), a selectivity index of 1243, and a resistance index of 0.5.

The first intermolecular interrupted imino-Nazarov reaction: Expeditious access to carbocyclic nucleoside analogues

The analogous imino-variant of the Nazarov reaction suffers from unfavorable energetics associated with the ring closure process, thereby limiting the utility of this class of reactions. In this report, the realization of the first intermolecular interrupted imino-Nazarov reaction utilizing silylated pyrimidine derivatives as nucleophilic trapping partners culminated in an expedient synthetic route to carbocyclic nucleoside analogues. The potential application of silylated nucleobases to intercept the oxyallyl cation in other variants of the Nazarov reaction provides vast opportunities to develop new strategies for the formation of carbocyclic nucleoside analogues.

Thermodynamics of various F420 coenzyme models as sources of electrons, hydride ions, hydrogen atoms and protons in acetonitrile

32 F420 coenzyme models with alkylation of the three different N atoms (N1, N3 and N10) in the core structure (XFH-) were designed and synthesized and the thermodynamic driving forces (defined in terms of the molar enthalpy changes or the standard redox potentials in this work) of the 32 XFH- releasing hydride ions, hydrogen atoms and electrons, the thermodynamic driving forces of the 32 XFH releasing protons and hydrogen atoms and the thermodynamic driving forces of XF- releasing electrons in acetonitrile were determined using titration calorimetry and electrochemical methods. The effects of the methyl group at N1, N3 and N10 and a negative charge on N1 and N10 atoms on the six thermodynamic driving forces of the F420 coenzyme models and their related reaction intermediates were examined; the results show that seating arrangements of the methyl group and the negative charge have remarkably different effects on the thermodynamic properties of the F420 coenzyme models and their related reaction intermediates. The effects of the substituents at C7 and C8 on the six thermodynamic driving forces of the F420 coenzyme models and their related reaction intermediates were also examined; the results show that the substituents at C7 and C8 have good Hammett linear free energy relationships with the six thermodynamic parameters. Meanwhile, a reasonable determination of possible reactions between members of the F420 family and NADH family in vivo was given according to a thermodynamic analysis platform constructed using the elementary step thermodynamic parameter of F420 coenzyme model 2FH- and NADH model MNAH releasing hydride ions in acetonitrile. The information disclosed in this work can not only fill a gap in the chemical thermodynamics of F420 coenzyme models as a class of very important organic sources of electrons, hydride ions, hydrogen atoms and protons, but also strongly promote the fast development of the chemistry and applications of F420 coenzyme.

Synthesis of indoxylic acid esters by rhodium-catalyzed carbene n-h insertion and thermal cyclization

Reaction between diethyl diazomalonate and a range of N-alkylanilines in the presence of a catalytic amount of rhodium(ii) acetate dimer afforded carbene N-H insertion to produce anilinomalonates in modest-to-good yields. Upon heating to a high temperature for a short time, the anilinomalonates underwent thermal cyclization to indoxylic acid esters.

Synthesis of 2-oxindoles via ‘transition-metal-free’ intramolecular dehydrogenative coupling (IDC) of sp2 C-H and sp3 C-H bonds

The synthesis of a variety of 2-oxindoles bearing an all-carbon quaternary center at the pseudo benzylic position has been achieved via a ‘transition-metal-free’ intramolecular dehydrogenative coupling (IDC). The construction of 2-oxindole moieties was carried out through formation of carbon-carbon bonds using KOt-Bu-catalyzed one pot C-alkylation of beta-N-arylamido esters with alkyl halides followed by a dehydrogenative coupling. Experimental evidences indicated toward a radical-mediated path for this reaction.

LDA-promoted decomposition of benzenesulfenamides. A route to aminyl radicals by dioxygen oxidation of lithium amides

The LDA-promoted decomposition of N-monosubstituted sulfenamides 1a-d occurs through the formation of thioaminyl anions, which undergo oxidation either at sulfur, with formation of sulfonamides, or at nitrogen, with formation of thioaminyl radicals, depending on the nature of the 4′-substituent. The reaction of N,N-disubstituted sulfenamides 1e-h proceeds through the intermediacy of a lithium complex capable of generating aminyl radicals via sulfenyl group transfer to the di-iso-propylamido anion and subsequent aerial oxidation of the resulting lithium amides 3e-h.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C10H7NO4, you can also check out more blogs about33282-15-4
