Potentiometric investigation of acid-base equilibria of two new pyrimidine derivatives in various methanol-water media [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
The acid-base properties of 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one (L1) and 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione (L2) were investigated potentiometrically at an ionic strength of 0.10M(LiCl) in 19.8, 33.6 and 55.9 % (v/v) methanol ...

Gravin orchestrates protein kinase A and 2-adrenergic receptor signaling critical for synaptic plasticity and memory [PDF]

open access: yes, 2012
A kinase-anchoring proteins (AKAPs) organize compartmentalized pools of protein kinase A (PKA) to enable localized signaling events within neurons. However, it is unclear which of the many expressed AKAPs in neurons target PKA to signaling complexes ...

DataSheet_1_Lactate increases tumor malignancy by promoting tumor small extracellular vesicles production via the GPR81-cAMP-PKA-HIF-1α axis.docx

open access: yes, 2022
Lactate and tumor cell-derived extracellular vesicles (TEVs) both contribute to tumor progression. However, it is still unclear whether lactate can accelerate tumor development by directly promoting TEV production.

Predicting the pKa Values of the Deprotonation Equilibria of Benzenonium Carbocations

open access: yes, 2022
The pKa(H) value of the benzenonium carbocation (C6H7+, cy-clohexadienyl cation, Wheland intermediate) is −24.3 [1]. The Hammett’s reaction constant (ρ) value for the deprotonation equilibrium is 14.3 [2].

The role of type 4 phosphodiesterases in generating microdomains of cAMP: Large scale stochastic simulations [PDF]

open access: yes, 2010
Cyclic AMP (cAMP) and its main effector Protein Kinase A (PKA) are critical for several aspects of neuronal function including synaptic plasticity. Specificity of synaptic plasticity requires that cAMP activates PKA in a highly localized manner despite ...

Control of PKA stability and signalling by RING ligase praja2 [PDF]

open access: yes, 2010
Ligand-mediated activation of G-Protein Coupled Receptors (GPCRs) mobilises compartmentalised pulses of second messengers like cAMP. The main cellular effector of cAMP is Protein Kinase A (PKA) which is assembled as inactive holoenzyme consisting of two ...
