THAM acetate
Based on 1 publication(s) in Google Scholar
THAM acetate is a low-toxicity amino alcohol buffer, a CO2-consuming proton acceptor that buffers carbon dioxide and acid both in vitro and in vivo. THAM acetate binds protons to form bicarbonate, reduces PaCO2, and induces intracellular alkalization, thereby ameliorating hypercapnia-induced elevation of pulmonary blood vessels and pulmonary arterial pressure. THAM acetate may cause PaCO2 rebound, hypoglycemia, and respiratory depression. THAM acetate removes amniotic epithelium and preserves the basement membrane, but depletes extracellular matrix and reduces the adhesion rate of limbal epithelial cells. THAM acetate can act as a CO2 carrier to enhance the productivity and carbon utilization rate of Scenedesmus obliquus. THAM acetate is a key component of buffer solutions used in various biological, cell culture, biochemical, and molecular biology applications.

Biological Activity
THAM (5 min) induces intracellular alkalization in human HepG2 hepatocytes perfused with acidotic artificial media, with a larger effect in the presence of low extracellular non-bicarbonate buffer compared to high extracellular non-bicarbonate buffer[3].
THAM (110 μL) acetate induces intracellular alkalization in human HepG2 hepatocytes bathed in acidotic human blood[3].
THAM (2-8 mmol/L; 40 min) acetate enhances CO2 gas absorptivity and total inorganic carbon storage capacity of modified BG-11 medium, with the highest TIC absorption observed at 8 mmol·L-1[5].
THAM (2-8 mmol/L; 8 days) acetate improves biomass productivity of Scenedesmus dimorphus in indoor shake flask culture, while also increasing polyunsaturated fatty acid content and showing no biodegradation over 8 days[5].
THAM (6 mmol/L; 8 days) acetate increases biomass areal productivity of Scenedesmus dimorphus by 32-33% and CO2 utilisation efficiency by 6-12% in outdoor 2 m2 raceway pond culture, while also increasing polyunsaturated fatty acid content[5].

Animal Model:Piglets (23.0-30.5 kg body weight; acute respiratory distress syndrome induced by repeated lung lavages with 30 mL/kg 37-39 °C normal saline, eight total)[2]
-
Dosage:Calculated to normalize pH and provide lasting effect
-
Administration:i.v.; continuous infusion; 1 hour (6 animals); 3 hours (6 animals)
-
Result:Increased arterial pH above 7.4, decreased PaCO2, and increased base excess to 13.8 mEq/L (1-hour group) and 16.0 mEq/L (3-hour group) at 60 minutes.
Reduced pulmonary vascular resistance to 423 dyn·s/m5 (1-hour group) and 373 dyn·s/m5 (3-hour group) at 60 minutes, compared to 572 dyn·s/m5 in controls.
Rebounded PaCO2 to 15.2 kPa (1-hour group) and 22.6 kPa (3-hour group) at 6 hours post-infusion cessation.
Maintained elevated base excess at 10.2 mEq/L (1-hour group) and 27.8 mEq/L (3-hour group) at 6 hours post-infusion cessation.
Decreased pH to levels similar to controls by 6 hours post-infusion cessation.
Lowered pulmonary vascular resistance to 329 dyn·s/m5 (1-hour group) and 255 dyn·s/m5 (3-hour group) at 6 hours, compared to 450 dyn·s/m5 in controls.
Increased cardiac index to 5.0 L/min/m2 in the 3-hour group at 6 hours, compared to 3.5 L/min/m2 in controls.
Decreased arterial sodium concentration during infusion and increased arterial potassium concentration during infusion.
Showed no significant differences in lung mechanics (functional residual capacity, respiratory system compliance) between groups.
Increased lung tissue IL-6 concentration to 11.8 pg/mg protein in the 3-hour group, with no significant differences vs. controls for TNF-α or IL-1β.
