Eight Indole Alkaloids from the Roots of Maerua siamensis and Their Nitric Oxide Inhibitory Effects

open access: yesMolecules, 2022
Maerua siamensis (Capparaceae) roots are used for treating pain and inflammation in traditional Thai medicine. Eight new indole alkaloids, named maeruanitriles A and B, maeroximes A–C, and maeruabisindoles A–C, were isolated from them.

Cloning and Overexpression of Strictosidine β-D-Glucosidase Gene Short Sequence from Catharanthus roseus in Escherichia coli [PDF]

open access: yesAdvanced Pharmaceutical Bulletin, 2019
Purpose: Strictosidine-β-D-glucosidase (SGD) is considered as a key enzyme in the production of bisindole alkaloids in Catharanthus roseus. The present study illustrated the production of a short sequence of this enzyme in Escherichia coli without codon ...

Ligand-Based Pharmacophore Mapping and Virtual Screening for the Search of Biguanide-Like Molecules With Antidiabetic Potentials Targeting Liver Kinase B1. [PDF]

open access: yesBiochem Res Int
Type 2 diabetes mellitus (T2DM) is a state where the body’s glucose metabolism is compromised. AMP‐activated protein kinase, or AMPK, has an important part to play in glucose metabolism, and the liver kinase B1 (LKB1) protein functions as a major upstream kinase for AMPK activation, thereby making it appealing therapeutic targets for treating and ...

Synthesis of Bisindole Alkaloids from the Apocynaceae Which Contain a Macroline or Sarpagine Unit: A Review

open access: yesMolecules, 2016
Bisindole natural products consist of two monomeric indole alkaloid units as their obligate constituents. Bisindoles are more potent with respect to their biological activity than their corresponding monomeric units.

Biotransformation Of l‐Tryptophan To Produce Arcyriaflavin A With Pseudomonas putida KT2440

open access: yesChemBioChem, Volume 24, Issue 23, December 1, 2023., 2023
Arcyriaflavin A was produced in Pseudomonas putida KT2440 using genes from Lentzea aerocolonigenes. Cultivation conditions and supply of the precursor l‐tryptophan were optimized. Genetic engineering of outer membrane vesicle release and cultivation with polyurethane adsorbent resulted in product enrichment in the supernatant.

3-[4-(1H-indol-3-yl)-1,3-thiazol-2-yl]-1H-pyrrolo[2,3-b]pyridines, nortopsentin Analogues with antiproliferative activity [PDF]

open access: yes, 2015
A new series of nortopsentin analogues, in which the imidazole ring of the natural product was replaced by thiazole and the indole unit bound to position 2 of the thiazole ring was substituted by a 7-azaindole moiety, was efficiently synthesized.

Facilitating biomimetic syntheses of borrerine derived alkaloids by means of flow-chemical methods [PDF]

open access: yes, 2015
Flow chemistry is widely used nowadays in synthetic chemistry and has increasingly been applied to complex natural product synthesis. However, to date flow chemistry has not found a place in the area of biomimetic synthesis.

Assessment of Mechanisms Involved in Antinociception Produced by the Alkaloid Caulerpine

open access: yesMolecules, 2014
In previous works we showed that oral administration of caulerpine, a bisindole alkaloid isolated from algae of the genus Caulerpa, produced antinociception when assessed in chemical and thermal models of nociception.
