Search for alkaloids on callus culture of Passiflora alata

open access: yesBrazilian Archives of Biology and Technology, 2010
Preliminary work on Passiflora alata leaves failed to detect harmane alkaloids using LC. The aim of this work was to investigate the production of harmane alkaloids through the cell culture of P. alata, inducing its precursor (L-tryptophan).

Studies with Arylhydrazono-3-oxopropanals:A novel route to synthesis of substituted pyrazoles, oxoalkanonitrile and glyoxalonitrile containing sulfa drug moieties [PDF]

open access: yes, 2008
Coupling of enaminones 1 with diazonium salts gave thehydrazonopropanals 3a-h. Compound 3 react with ω-bromoacetophenone or α-chloroacetanilide to yield 5 and 8. These compounds were cyclized smoothly into 6 and 9 respectively.

Conformational dynamics in insulin receptor kinase reveal a type III allosteric pocket

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Allosteric modulation is a promising strategy for selective kinase inhibition, yet structural insights into allosteric pockets remain limited across the human kinome. In this work, we present comprehensive characterization of a type III allosteric pocket in the insulin receptor kinase (IRK), integrating structural, conformational, and ...
