Dissociation Constants of Thiolactic Acid
The acid dissociation constants of thiolactic acid have been determined potentiometrically and polarographically at three diffrent temperatures, \(pK_{D_1}\)values· have been found to be 3·63, 3·66 and 3·70 and \(pK_{D_2}\) values as 10.24, 10·18 and 10·11 at 20°,30° and 40° respectively.

The acid dissociation constant of three benzimidazoles, namely 2,2′-bibenzo[d]imidazole, 2,5′-bibenzo[d]imidazole, and 5,5′-bibenzo[d]imidazole, have been investigated by means of density functional theory calculations in gas phase and in aqueous ...

Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Dissociation Constants of Hexosephosphoric Acids.
Hexosediphosphoric acid from yeast and hexosemonophosphoric acid from muscle (lactacidogen) were kindly made available from preparations by Professor Embden. Electrometric titration showed both stronger than pure phosphoric acid in the region of the first and, more conspicuously, in that of the second dissociation constant.

Influence of Metal Ion Complexation on the Acid Dissociation of 4'-Carboxybenzo-24-Crown-8 in an Ethanol-Water Mixture [PDF]
A spectrophotometric method was used to determine the acidity constant of 4'-carboxybenzo-24-crown-8 in 52% (w/w) ethanol-water mixture. The acid dissociation constant, Ka, was found to increase in the presence of Na+, K+, Rb+, Cs+ and Tl+ ions.

The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Dissociation Constants and Dissociation Velocities of Substituted Pyruvic Acids [PDF]
IT has been shown1 that weak acids are very often reduced polarographically in two steps. The more positive step belongs to the undissociated acid, the more negative to the acid ion. The total height of these two steps remains constant; but their ratio is changed in a characteristic way with the pH of the solution. If we plot this ratio against the pH,
