Preparation of new alkyne-modified ansamitocins by mutasynthesis

Harmrolfs, Kirsten; Mancuso, Lena; Drung, Binia; Sasse, Florenz; Kirschning, Andreas (Frankfurt am Main : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2014)

The preparation of alkyne-modified ansamitocins by mutasynthetic supplementation of Actinosynnema pretiosum mutants with alkyne-substituted aminobenzoic acids is described. This modification paved the way to introduce a ...
Unprecedented deoxygenation at C-7 of the ansamitocin core during mutasynthetic biotransformations

Knobloch, Tobias; Draeger, Gerald; Collisi, Wera; Sasse, Florenz; Kirschning, Andreas (Frankfurt am Main : Beilstein-Institut Zur Förderung der Chemischen Wissenschaften, 2012)

We describe the unprecedented formation of six ansamitocin derivatives that are deoxygenated at C-7 of the ansamitocin core, obtained during fermentation experiments by employing a variety of Actinosynnema pretiosum mutants ...
