Abstract
Asymmetric total synthesis of cyclotetradepsipeptide beauveamide A has been achieved for the first time. A macrolactamization strategy involving two possible sites has been explored to find the most effective route for cyclization. A late-stage functionalization approach has been adopted for easy access of non-natural analogues of beauveamide A for further biological evaluation. Interestingly, the anticancer activity of one of the synthesized analogues was better than that of the parent natural product.

Fourth-Generation Analogues of the Anticancer Peptaibol Culicinin D: Probing the Effects of Hydrophobicity and Halogenation on Cytotoxicity. SYNTHESIS-STUTTGART 2021.

Abstract
AbstractPreliminary results of the effect of hydrophobicity and halogenation on the cytotoxicity of the anticancer peptaibol culicinin D are reported. Building on previous work, the synthetically challenging (2S,4S,6R)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid and (2S,4R)-2-amino-4-methyldecanoic acid building blocks were replaced with derivatives of l-phenylalanine and 2-aminodecanoic acid, respectively. Substitution of (2S,4S,6R)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid with l-4,4′-biphenylalanine yielded an analogue that was tenfold more potent than the natural product and was also the most hydrophobic analogue, as judged by an antiproliferative IC50 assay and logD calculations; these results suggest that the potency of culicinin D may be governed by its hydrophobicity. However, the introduction of halogenated moieties into the peptide sequence generated analogues that were similarly potent, although not necessarily hydrophobic. Thus, the parameters regulating the cytotoxicity of culicinin D, and by extension other peptaibols, are multimodal and include both halogenation and hydrophobicity.

Abstract
This review describes our efforts toward achieving catalytic asymmetric total synthesis of leucinostatin A, a compound that interferes with the tumor-stroma interaction. The synthesis utilizes four catalytic asymmetric reactions, including direct-type reactions exemplified by high atom-economy, and three C-C bond forming reactions. Thorough analysis of the NMR data, HPLC profiles, and biologic activity led us to unambiguously revise the absolute configuration regarding the 6-position of the AHMOD residue side chain from S (reported) to R. Other examples of previously reported important studies on the stereoselective synthesis of HyLeu and AHMOD are also described.

Synthesis and antiproliferative activity of C- and N-terminal analogues of culicinin D. Bioorg Med Chem Lett 2020; 30:127331. [PMID: 32631536 DOI: 10.1016/j.bmcl.2020.127331] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 06/02/2020] [Accepted: 06/05/2020] [Indexed: 11/20/2022]
Abstract
Culicinin D (1), a 10 amino acid peptaibol containing several unusual residues, has been shown to exhibit potent anticancer activity. Previous work in our group towards developing a structure-activity relationship (SAR) for this peptaibol has concentrated on replacement of the synthetically challenging AHMOD (3) and AMD (4) residues, resulting in the discovery of analogues with equivalent or better potency and simplified synthesis. The SAR of this peptaibol is extended in this work by investigating the effect of the N-terminal lipid tail and C-terminal amino alcohol, revealing the key contribution of each of these moieties on antiproliferative activity in a panel of breast and lung cancer cell lines.

Abstract
Many methods have been developed for attaching an alcohol functionality to a solid support. However, not all of these methods are used to obtain peptide alcohols. In this Minireview, we will discuss several of the most important methods and approaches for the synthesis of peptide alcohols and the attachment of hydroxy groups to a solid support for the synthesis of cyclic peptides. Some of the methods include the use of functionalized Wang resin and the attachment of an alcohol to an enol ether resin. We also discuss the use of the chlorotrityl resin, one of the most common linkers used to obtain peptide alcohols. In addition, we outline the recently developed resins with the Rink, Ramage and Sieber handles. The majority of these methods have been used to synthesize many important drugs, such as octreotide and the antibiotic peptaibols.

Abstract
Culicinin D (1), a 10 amino acid peptaibol originally isolated from Culicinomyces clavisporus, exhibits potent activity against a range of cancer cell lines. Building on our previous work exploring the structure-activity relationship (SAR) of the unusual (2S,4S,6R)-AHMOD residue, a series of analogues of culicinin D were prepared to further investigate the SAR of these peptaibols. Alanine scanning of a potent and readily accessible analogue 23 revealed the effect of each residue on antiproliferative activity, and a small panel of analogues were prepared to explore the SAR of the non-natural amino acid residue (2S,4R)-AMD. Results from the alanine scan were used to design an expanded library of culicinin D analogues, leading to the discovery of cyclohexylalanine analogue 52, which exhibited better antiproliferative activity than the natural product 1.
