PROCESS FOR THE PREPARATION OF POLYMORPH FORM B OF TREPROSTINIL DIETHANOLAMINE SALT

The invention relates to a robust and reproducible process for the preparation of polymorph form B of treprostinil diethanolamine salt, comprising the following steps: a. treprostinil is dissolved in methanol, b. to the solution of step a) diethanolamine or its methanol solution is added, c. the reaction mixture of step b) is agitated till dissolution, d. when salt formation is completed in step c), first portion of an aprotic solvent is added to the solution, e. the solution of step d) is filtered to remove insoluble impurities, f. the filtrate of step e) is seeded with polymorph form B of treprostinil diethanolamine salt, g. to the crystal suspension obtained in step f) a second portion of the aprotic solvent is added, h. the suspension of step g) is agitated until crystallisation is completed, i. the crystals are separated, washed and dried.

STAT3 inhibitor formulation

Disclosed is a salt prepared from the STAT3 inhibitor known as 2-hydroxy-4-[[2-[[(4-methylphenyl)sulfonyl]oxy]acetyl]amino] benzoic acid and 2-amino-2-(hydroxymethyl)-1,3-propanediol. The salt is soluble in water and stable for extended periods of time. Further provided are pharmaceutical compositions comprising the salt and methods of administering the salt to prevent and treat cancer, such as breast cancer.

Biological buffers with wide buffering ranges
10927279 · 2021-02-23 ·

Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.
