Description of HBTU

IC50: Not available.

HBTU (2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexauorophosphate), a coupling reagent commonly used in solid phase peptide synthesis. After being introduced in 1978, this agent shows popularity in chemistry and industry use due to its mild activating properties. Moreover, it also shows resistance against racemization. Low tendency for racemization is a key requirement for peptide synthesis. Especially for solid phase peptide synthesis, quantitative yields with short reaction times are crucial in order to make the synthesis of large peptides feasible. [1]

In vitro: Peptide synthesis relied mostly on efficient and safe coupling reagents. HBTU was proved to transform carboxylic acids into azides efficiently and practically. The process might be applied to a wide range of carboxylic acids including N-protected amino acids. In addition, HBTU was of great value in one-pot synthesis of dipeptidyl urea esters, ureas, and carbamates from acids. The advantages of HBTU included the following points: 1) Non-explosive and therefore more suitable for solution/solid phase peptide synthesis. 2) High solubility and stability in classical solvents. 3) Feasible for colorimetric reaction monitoring. [2]

In vivo: So far, no in vivo data has been reported.

Clinical trial: So far, no clinical trial has been conducted.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
