The rate and extent of binding of methazolamide to human erythrocytes was studied in vitro. All experiments were carried out at physiological temperature (37C) and pH (7.4). Methazolamide (MTZ) buffer concentrations were analyzed by HPLC. Distributional equilibrium between buffer and washed red blood cells was achieved after 1 hr. Results of equilibrium studies were consistent with two classes of binding sites for MTZ within the erythrocyte: a low affinity, high capacity site (CA-I) and a high… 

Novel 1,3,4-Oxadiazole Fused Thiadiazole Derivatives: Synthesis and study of Anticancer Activities

In search of novel anticancer agents, a series of 1,3,4-oxadiazole derivatives (12a-j) containing 1,3,4-thiadiazole moieties were synthesized, and their structures were confirmed by 1HNMR, 13CNMR

Synthesis of new chiral 1,3,4-thiadiazole-based di- and tri-arylsulfonamide residues and evaluation of in vitro anti-HIV activity and cytotoxicity

A series of new chiral 1,3,4-thiadiazole-based bis-sulfonamides 4a–4w and tri-solfonamide analogue 5 was synthesized and evaluated as anti-HIV agents and exhibited significant cytotoxicity of > 4.09 μM and could be a promising antiproliferative agent.

Simulation of the Pharmacokinetic Profile of Methazolamide in Blood: Effect of Erythrocyte Carbonic Anhydrase Binding on Drug Disposition

The influence of the kinetics of drug binding to CA isozymes I and II on the pharmacokinetic profile of MTZ in vivo was investigated using computer simulations for single and multiple oral dosing regimens and a physical model was developed that described MTZ absorption, distribution, and elimination in vivo.



Uptake of acetazolamide by human erythrocytes in vitro.

Erythrocyte accumulation of acetazolamide appeared to be a composite of two processes: a nonlinear, saturable process and a linear, diffusion-controlled process.

Effect of salicylate on serum protein binding and red blood cell uptake of acetazolamide in vitro.

Results indicate that while competitive binding effects, which may alter unbound drug concentration-time profiles and potentially impact on toxicity, do occur, alterations in red cell membrane permeability, which could adversely affect carbon dioxide transport, are not of significance.

Erythrocytes and the Transport of Drugs and Endogenous Compounds

This review considers the significance and measurement of endogenous compounds and drugs on erythrocytes. Part I examines literature examples where a direct measurement of hydrocortisone, phenytoin

Nonlinear dorzolamide pharmacokinetics in rats: concentration-dependent erythrocyte distribution and drug-metabolite displacement interaction.

Ex vivo and in vitro assessments of the equilibrium RBC/ plasma concentration ratio indicated that metabolite displacement of dorzolamide from enzyme binding sites in RBC occurs at pharmacologically relevant concentrations.

Time course and disposition of methazolamide in human plasma and red blood cells.

Temporal patterns of methazolamide concentrations in plasma and red blood cells were obtained following single- and multiple-dose oral administration of the drug, indicating nonlinearity in the binding of thedrug to the red blood cell carbonic anhydrase.

Blood disposition and urinary excretion kinetics of methazolamide following oral administration to human subjects

The pharmacokinetic disposition of methazolamide was studied in five healthy volunteers following administration of a single oral dose and the model estimate of elimination half‐life was consistent with drug binding to a high affinity carbonic anhydrase isozyme in the erythocyte.
