Techniques: Synthesis - Sound on Sound

The coupling sites were chosen to maximize the convergency of the synthesis including that of the three subunits, to prevent late-stage racemization of carboxylate-activated phenylglycine-derived residues, and to enlist β-sheet preorganization of an acyclic macrocyclization substrate for 49-membered ring closure.

The compounds emerged from the discovery of a site and functionalization strategy for the preparation of a vinblastine analogue that contains a single heavy atom exchange (C20′ NH2 for OH). Its acylation provided the now readily accessible vinblastine analogues in three steps from commercially available materials that, unlike acylated derivatives of the alcohol itself (inactive), not only increase binding affinity to tubulin (on target affinity) and potency in cell-based assays, but also simultaneously disrupt efflux by Pgp (off target source of resistance). It is a tribute to the advances in organic synthesis that such detailed systematic studies can now be conducted on a natural product of a complexity as vinblastine once thought refractory to such approaches.

8 Tips to Consider When Arranging Electronic Music : …

Whether it is in the context of drug discovery and the design of small molecules that selectively bind a therapeutic target, the delineation of a molecular mechanism of action of a natural product or chemical probe, the examination of signal transduction by endogenous signaling molecules, or the study of the interaction of substrates or inhibitors with an enzyme, the identification of structural features responsible for intermolecular ligand binding affinity and selectivity is fundamental to understanding and advancing science at the chemistry–biology interface. For chemists and medicinal chemists, the impact of not just the molecule, a substructure in the molecule, or even a substituent or functional group within the molecule, but the impact and nuanced role of even an individual atom in the molecule is fascinating, often exhibiting a remarkable influence. Even in fields not directly related to understanding the behavior of biologically active molecules, including reagent design, ligand development, catalysis, molecular recognition, complex molecule total synthesis, material science, and many others, the decisive role a single atom in a molecule can play is well appreciated.

The natural products are exceptionally potent antitumor compounds that derive their activity through a sequence selective DNA alkylation. Our studies provided not only total syntheses of the natural products, but also the characterization of their DNA alkylation properties, including that of their unnatural enantiomers. In these studies, we defined their DNA alkylation selectivity, rates, and reversibility, isolated and characterized their adenine N3 adducts, and defined their stereoelectronically controlled reaction regioselectivity. We defined the source of their alkylation selectivity as arising from their noncovalent binding selectivity preferentially in the narrower, deeper AT-rich minor groove (shape selective recognition), and identified the unusual source of catalysis for the alkylation reaction that is derived from a DNA binding induced conformation change that disrupts the stabilizing vinylogous amide conjugation (shape dependent catalysis). We demonstrated and quantified the fundamental role the hydrophobic character of the compounds plays in the expression of the biological activity, driving the intrinsically reversible DNA alkylation reaction, and defined the stunning magnitude of its effect (hydrophobic binding-driven-bonding). In collaboration with Walter Chazin, we provided high-resolution NMR-derived structures of the natural products and their unnatural enantiomers bound to DNA () and established that they are subject to an exquisite “target-based activation”. In the course of these studies, we introduced a convenient M13-derived alternative to 32P-end-labeling of restriction fragments for DNA cleavage studies. Fundamental relationships between structure and reactivity or structure and activity, and their contributions to the DNA alkylation properties and biological activity of the natural products, were established through the examination of more than 2000 analogues of the natural products that contained deep-seated structural changes (e.g., CBI). A compilation of the data derived from more than 30 deep-seated modifications, many of which entailed single heavy atom changes, resulted in the establishment of a predictive parabolic relationship between the alkylation subunit reactivity and the resulting cytotoxic potency that spanned a 104–106 range of reactivity and activity (). Presumably, this fundamental relationship reflects the fact that the compound must be sufficiently stable to reach its biological target yet remain sufficiently reactive to alkylate DNA once it does.
