Synthesis and in vitro cytotoxicity of cryptophycins and related analogs

Several members of the Cryptophycin family were synthesised using a straightforward convergent approach. The proposed synthetic route was used to prepare novel analogs of Cryptophycins A and B in which the benzylic epoxide moiety was replaced by alternate electrophilic functions. The effect of these modifications on cytotoxic activity was determined on several tumor cell lines.

Development of a Kilogram-Scale Synthesis of a Novel MC1R Agonist

Herein, we report the kilogram-scale synthesis of CD08108, a novel MC1R agonist. This synthesis has been developed to produce the first batches of this compound for preclinical and clinical studies. Two amido couplings were used to synthesize the backbone of the API. Improvements have been made to isolate crystalline intermediates and to remove all column chromatographic steps. Crystallization of the final API was monitored by DSC in-process control during slurry ripening of the amorphous suspension of the hydrochloride salt.

Total synthesis of cryptophycin-24 (arenastatin A) amenable to structural modifications in the C16 side chain

Two efficient protocols for the synthesis of tert-butyl (5S,6R,2E,7E)-5-[(tert-butyldimethylsilyl)-oxy]-6-methyl-8-phenyl-2,7-octadie noate, a major component of the cryptophycins, are reported. The first utilized the Noyori reduction and Frater alkylation of methyl 5-benzyloxy-3-oxopentanoate to set two stereogenic centers, which became the C16 hydroxyl and C1′ methyl of the cryptophycins. The second approach started from 3-p-methoxybenzyloxypropanal and a crotyl borane reagent derived from (-)-alpha-pinene to set both stereocenters in a single step and provided the dephenyl analogue, tert-butyl (5S,6R,2E)-5-[(tert-butyldimethylsilyl)oxy]-6-methyl-2,7-octadienoate, in five steps. This compound was readily converted to the 8-phenyl compound via Heck coupling. The silanyloxy esters were efficiently deprotected and coupled to the C2-C10 amino acid fragment to provide desepoxyarenastatin A and its dephenyl analogue. The terminal olefin of the latter was further elaborated via Heck coupling. Epoxidation provided cryptophycin-24 (arenastatin A).

Synthesis of unit-B of cryptophycin-24 via Sharpless asymmetric dihydroxylation

A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of alpha-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of alpha-amino acid without the loss of chirality during the transformation.

Design, synthesis, and biological evaluation of the combinatorial library with a new spirodiketopiperazine scaffold. Discovery of novel potent and selective low-molecular-weight CCR5 antagonists.

We previously reported the discovery of several spirodiketopiperazine derivatives as potent CCR5 antagonists with anti-HIV activity. Herein, we describe in detail the identification of these lead compounds using a combinatorial chemistry approach. A novel spirodiketopiperazine scaffold was designed on the basis of the concept of the privileged structure of G-protein-coupled receptors (GPCRs). This new framework was obtained in acceptable yield with high purity from the readily prepared isonitrile resin through the Ugi reaction, sequential transformations, and cyclative cleavage. By measuring the inhibitory activity of each compound in the initial library against the intracellular calcium mobilization stimulated by MIP-1alpha, several compounds were found to show modest but selective CCR5 antagonistic activity. After the rapid evaluation of these hit compounds, several single-digit nanomolar, low-molecular-weight CCR5 antagonists that can potently block the infectivity and replication of laboratory and clinical strains of HIV as well as those of highly drug-resistant HIV variants with minimal cytotoxicity have been identified.
