Pure compound screening has previously identified the indolglyoxy lamidospermidine ascidian metabolites didemnidine A and B (2 and 3) to be weak growth inhibitors of Trypanosoma brucei rhodesiense (IC50 59 and 44 muM, respectively) and Plasmodium falciparum (K1 dual drug resistant strain) (IC50 41 and 15 muM, respectively), but lacking in selectivity (L6 rat myoblast, IC50 24 muM and 25 muM, respectively). To expand the structure-activity relationship of this compound class towards both parasites, we have prepared and biologically tested a library of analogues that includes indoleglyoxyl and indoleacetic “capping acids”, and polyamines including spermine (PA3-4-3) and extended analogues PA3-8-3 and PA3-12-3. 7-Methoxy substituted indoleglyoxylamides were typically found to exhibit the most potent antimalarial activity (IC50 10-92 nM) but with varying degrees of selectivity versus the L6 rat myoblast cell line. A 6-methoxyindolglyoxylamide analogue was the most potent growth inhibitor of T. brucei (IC50 0.18 muM) identified in the study: it, however, also exhibited poor selectivity (L6 IC50 6.0 muM). There was no apparent correlation between antimalarial and anti-T. brucei activity in the series. In vivo evaluation of one analogue against Plasmodium berghei was undertaken, demonstrating a modest 20.9% reduction in parasitaemia.

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.Synthetic Route of 3189-13-7, you can also check out more blogs about3189-13-7

A facile method for the synthesis of 3-cyanoacetyl indole derivatives mediated by propionic anhydride is described. These 3-cyanoacetylindole derivatives have been used in a starting material for the syntheses of various new compounds like (E)-2- ((1H-indol-3-yl)methylene)-3-oxoindolylnitrile, 3-acetylcoumrineindoles, 3-cyanoacetylquinones, 3-cyanoacetylindolyl chalcones, E-2-benzyl-3-(1H-indol-3yl)acrylonitriles, 3-(1H-indol-3- yl)-3-oxopropanamides and 3-acetylindoles.

We have recently developed palladium-catalyzed methods for direct arylation of indoles (and other azoles) wherein high C-2 selectivity was observed for both free (NH)-indole and (NR)-indole. To provide a rationale for the observed selectivity (“nonelectrophilic” regioselectivity), mechanistic studies were conducted, using the phenylation of 1-methylindole as a model system. The reaction order was determined for iodobenzene (zero order), indole (first order), and the catalyst (first order). These kinetic studies, together with the Hammett plot, provided a strong support for the electrophilic palladation pathway. In addition, the kinetic isotope effect (KIEH/D) was determined for both C-2 and C-3 positions. A surprisingly large value of 1.6 was found for the C-3 position where the substitution does not occur (secondary KIE), while a smaller value of 1.2 was found at C-2 (apparent primary KIE). On the basis of these findings, a mechanistic interpretation is presented that features an electrophilic palladation of indole, accompanied by a 1,2-migration of an intermediate palladium species. This paradigm was used to design new catalytic conditions for the C-3 arylation of indole. In case of free (NH)-indole, regioselectivity of the arylation reaction (C-2 versus C-3) was achieved by the choice of magnesium base.

A series of novel 2-amino-3,4,5 trimethoxyaroylindole derivatives was synthesized and evaluated against selected human cancer cell lines of breast (MCF-7) and colon (HT-29). Introduction of an amino group at the C-2 position on ring A of 3,4,5-trimethoxyaroylindole derivatives resulted in novel compounds, i.e., 2-amino-3,4,5-trimethoxyaroylindole derivatives exhibiting excellent cytotoxic activity against human cancer cell lines. Substitution with methoxy group at R6 in 2-amino-3,4,5-trimethoxyaroylindole 5d exhibited excellent cytotoxic activity against MCF-7 (0.013 muM) and colon HT-29 (0.143 muM) indicating slightly higher potency than Combretastatin A-4. Molecular modeling studies of 2-amino-3,4,5-trimethoxyaroylindole derivatives have similar structural alignment as colchicine in protein (PDB code: 1SA0) and exhibited hydrogen bond interaction between para position of 3,4,5-trimethoxyphenyl ring with CYS 241 and N-H molecule of indole ring with Val 315 of receptor molecule.

A novel triphenylphosphine-mediated direct trifluoromethylthiolation of indole derivatives using trifluoromethanesulfonyl chloride as the SCF3 source was developed. Sodium iodide facilitated this transformation by generating iodine in situ which was found to accelerate this transformation. The use of a transition metal-free protocol, readily available reagents, and mild reaction conditions allowed this protocol to be easily scaled up.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3189-13-7 is helpful to your research. Recommanded Product: 3189-13-7

A new entry into pyrroloiminoquinone marine alkaloids, makaluvamines, has been developed. The key 1,3,4,5-tetrahydropyrrolo[4,3,2-de]quinoline intermediates 11 and 18 were prepared by aryne-mediated cyclization of the 4- chloro-6-methoxytryptamine derivatives 10 and 17, respectively. The requisite substituents at the indole 4- and 3-positions of 10 and 17 were efficiently assembled by sequential use of directed lithiation of 1-triisopropylsilyl-6- methoxygramine (6) and fluoride ion-induced elimination-addition of the methiodide of 4-chloro-l-triisopropylsilyl-6-methoxygramine (7) as key reactions.
