Tubulysin D is one of the most potent derivatives among the tubulysins isolated from the myxobacterial species Archangium geophyra and Angiococcus disciformis. Tubulysin D is a novel tetrapeptide that displays potent antitumor activity and leads to cell cycle arrest and apoptosis by inhibiting tubulin polymerization with an IC50 of 1.7 μM[1]. Tubulysin displays extremely potent cytotoxic activity in mammalian cells, including multidrug-resistant cell lines, with IC50 values in the lower nanomolar range[2]. IC50: 1.7 μM (Tubulin)[1]
Tubulysin D has IC50s of 4.7 pM, 3.1 pM, 670 pM and 13 pM for HL60, HCT116, MCF7, A549 cell lines antiproliferative activity, respectively[1].

Synthesis and biological evaluation of Tubulysin D analogs related to stereoisomers of tubuvaline
Bioorg Med Chem Lett 2011 Jan 1;21(1):431-4.PMID:21106374DOI:10.1016/j.bmcl.2010.10.118.
The synthesis and biological evaluation of stereoisomers in Tubulysin D are described. The stereoselective synthesis of all possible stereoisomers of C-11 and C-13 positions in Tubulysin D was achieved by employing 1'-epi-Tuv-Me, 3'-epi-Tuv-Me, and ent-Tuv-Me and their biological properties were evaluated. It is clear that the stereochemistries of the C-11 and C-13 positions in Tubulysin D have no practical impact on the inhibition of tubulin polymerization but play a role in the potent antiproliferative activities.
The total synthesis of Tubulysin D
J Am Chem Soc 2006 Dec 20;128(50):16018-9.PMID:17165738DOI:10.1021/ja067177z.
The first total synthesis of Tubulysin D is reported. The development and application of new tert-butanesulfinamide methods allowed for rapid syntheses of the tubuvaline and tubuphenylalanine fragments. Most significantly, a route was devised and implemented to introduce and carry forward the highly labile N,O-acetal functionality. Tubulysin D is the most active member of the tubulysin family, and the efficient synthetic route described herein will allow for the rapid syntheses of analogues to probe the biological activity of this important class of natural products.
Total syntheses of tubulysins
Chemistry 2010 Oct 11;16(38):11678-88.PMID:20734394DOI:10.1002/chem.201000963.
The total syntheses of tetrapeptides tubulysins D (1 b), U (1 c), and V (1 d), which are potent tubulin polymerization inhibitors, are described. The synthesis of Tuv (2), an unusual amino acid constituent of tubulysins, includes an 1,3-dipolar cycloaddition reaction of chiral nitrone D-6 derived from D-gulose with N-acryloyl camphor sultam (-)-9 employing the double asymmetric induction, whereas the synthesis of Tup (20), another unusual amino acid, involves a stereoselective Evans aldol reaction of (Z)-boron enolate generated from (S)-4-isopropyl-3-propionyl-2-oxazolidinone with N-protected phenylalaninal and a subsequent Barton deoxygenation protocol. We accomplished the total syntheses of tubulysins U (1 c) and V (1 d) by using these methodologies, in which the isoxazolidine ring was used as the effective protective group for γ-amido alcohol functionality. Furthermore, to understand the structure-activity relationship of tubulysins, we synthesized Tubulysin D (1 b) and cyclo-tubulysin D (1 e) from 2-Me and 20, and ent-tubulysin D (ent-1 d) from ent-2-Me and ent-20, respectively. The preliminary results regarding their biological activities are also reported.
Design, synthesis, and biological properties of highly potent Tubulysin D analogues
Chemistry 2007;13(34):9534-41.PMID:17828721DOI:10.1002/chem.200701057.
Ten analogues of Tubulysin D were synthesized and assayed against established mammalian cell lines, including cancer cells measuring inhibition of cell growth by an MTT assay. These experiments establish for the first time the essential features for the potent cytotoxicity of Tubulysin D. The activities of analogues 2 to 5 demonstrate that numerous modifications may be introduced at the C-terminus of the natural product with only modest loss in activity, while the activities of analogues 6 to 8 suggest that a basic amine must be present at the N-terminus to maintain activity. Most surprisingly, analogue 10 establishes that replacement of the chemically labile O-acyl N,O-acetal with the stable N-methyl group results in almost no loss in activity. In aggregate, these structure-activity relationships enable the design of analogues such as 11 that are smaller and considerably more stable than Tubulysin D but that maintain most of its potent cell-growth inhibitory activity.
First total synthesis of tubulysin B
Org Lett 2009 Dec 17;11(24):5567-9.PMID:19919080DOI:10.1021/ol902320w.
The first total synthesis of tubulysin B is described. The aziridine route to tubuphenylalanine (Tup) of the Tubulysin D/U-series could not be transferred to the synthesis of tubutyrosine (blue moiety). Therefore, tubutyrosine (Tut) was synthesized by a Wittig olefination/diastereoselective catalytic reduction sequence. Interestingly, the C-2 epimer of tubulysin B has a cytotoxic activity almost identical to the natural diastereomer.
