Trisoxazole Macrolides Potentiate the Microtubule Assembly and Antimitotic Activities of Taxanes

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Photoaffinity experiments identified tubulin as a new target of mycalolides. Though weakly cytotoxic, the trisoxazole macrolactone moiety enhanced paclitaxel's microtubule assembly and antimitotic effects. Molecular modeling studies suggested that MyC stabilizes α/β‐tubulin heterodimer interactions.

Inhibition of Wnt signalling and breast tumour growth by the multi-purpose drug suramin through suppression of heterotrimeric G proteins and Wnt endocytosis. [PDF]

open access: yes, 2016
Overactivation of the Wnt signalling pathway underlies oncogenic transformation and proliferation in many cancers, including the triple-negative breast cancer (TNBC), the deadliest form of tumour in the breast, taking about a quarter of a million lives ...

Serotonin 5‐HT7 receptor signaling in neuropsychiatric disorders

open access: yesBulletin of the Korean Chemical Society, EarlyView.
5‐HT7R recruits Gs, G12, and β‐arrestin signaling to regulate neuronal plasticity, circuit function, and kinase‐linked intracellular responses. This review summarizes how these pathway‐selective modules contribute to autism spectrum disorder, depression, and schizophrenia, highlighting 5‐HT7R as a pathway‐informed therapeutic target. Abstract Serotonin

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]

open access: yes, 1992
1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)

TARGETS FOR MAJORITY OF DRUGS: G PROTEIN-COUPLED RECEPTORS - THEIR STRUCTURE AND INTERACTIONS WITH BIOLIGANDS

open access: yesTASK Quarterly, 2021
G protein-coupled receptors (GPCRs) are the most frequent targets for many drugs. They form the largest superfamily of integral membrane proteins, of which more than 1000 members have the following common features: (i) All GPCRs form 7 hydrophobic a ...

Activation of phospholipase C beta 2 by the alpha and beta gamma subunits of trimeric GTP-binding protein [PDF]

open access: yes, 1993
Cotransfection assays were used to show that the members of the GTP-binding protein Gq class of alpha subunits could activate phospholipase C (PLC) beta 2.

Advances in GPCRs Associated With Wnt Signaling Within the Auditory System

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

The Role of G Protein Alpha Subunits in the Infection Process of the Gray Mold Fungus Botrytis cinerea

open access: yesMolecular Plant-Microbe Interactions, 2001
To identify signal transduction pathways of the gray mold fungus Botrytis cinerea involved in host infection, we used heterologous hybridization and a polymerase chain reaction (PCR)-based approach to isolate two genes (bcg1 and bcg2) encoding α subunits

On the roles of Mg in the activation of G proteins [PDF]

open access: yes, 2010
In this review, we highlight the evolution of our knowledge about the way Mg2+ participates in the activation of heterotrimeric G proteins, beginning with its requirement in hormonal stimulation of fat cell adenylyl cyclase (1969) and ending with ...
