  • Procedure for the purification of tiacumicin B
    Patent number: 9045515
    Abstract: The present invention relates to an improved process for the purification of tiacumicin B. Specifically, the invention relates to a simplified, optimised process for the purification of tiacumicin B from a fermentation broth, using chromatography techniques. In particular, the invention relates to a method for purifying tiacumicin B which comprises subjecting a liquid containing tiacumicin B to at least one hydrophobic interaction chromatography step. The process according to the invention is simpler than the processes according to the prior art, and can easily be used on a large scale for commercial production.

  • Process for the synthesis of pergolide
    Patent number: 7019140
    Abstract: A process for the synthesis of pergolide (Formula (I)) (D-6-n-propyl-8?methylmercaptomethylergo line) from acid 9,10-dihydrolysergic is herein disclosed. The process can be carried out without isolating most intermediates and is particularly convenient both from the yield and safety standpoint.

    Publication number: 20050124812
    Abstract: A process for the synthesis of pergolide (Formula (1)) (D-6-n-propyl-8?methylmercaptomethylergo line) from acid 9,10-dihydrolysergic is herein disclosed. The process can be carried out without isolating most intermediates and is particularly convenient both from the yield and safety standpoint. Moreover, pergolide thereby obtained is highly pure and can be conveniently transformed into pergolide mesylate.
