Abstract
A series of macrolactam analogues of the naturally occurring resorcylic acid lactone radicicol have been synthesised from methyl orsellinate in 7 steps, involving chlorination, protection of the two phenolic groups, and hydrolysis to the benzoic acid. Formation of the dianion and quenching with a Weinreb amide results in acylation of the toluene methyl group that is followed by amide formation and ring closing metathesis to form the macrocyclic lactam. Final deprotection of the phenolic groups gives the desired macrolactams whose binding to the N-terminal domain of yeast Hsp90 was studied by isothermal titration calorimetry and protein X-ray crystallography.

Abstract
The syntheses of a structurally simplified geldanamycin analogue 2 and two related compounds are described. Compound 2 conferred cytoprotection and quenched ROS and lipid peroxidation in a dose-dependent manner in Friedreich's ataxia (FRDA) lymphocytes at low micromolar concentrations. It also prevented ROS-induced damage of cellular lipid membranes and maintained the mitochondrial membrane potential of FRDA lymphocytes. In addition, 2 did not inhibit Hsp90 when tested at micromolar concentrations, exhibited no cytotoxicity, and afforded neuroprotection to differentiated SH-SY5Y cells under conditions of Aβ-induced cell toxicity.

Abstract
19-Substituted geldanamycin derivatives are efficient Hsp90 inhibitors, without the toxicity associated with the other benzoquinone ansamycins, thus giving them potential for use as molecular therapeutics in cancer and neurodegeneration. Here a new method of synthesising these important compounds is reported, eliminating the need for toxic metals and metalloids.

Abstract
Natural products have been fundamental in the development of new therapeutic agents predicated on the inhibition of heat shock protein 90 (Hsp90). This Perspective describes the influential role of the benzoquinone ansamycin geldanamycin and the resorcylic acid macrolactone radicicol not only in driving forward drug discovery programs but also in inspiring organic chemists to develop innovative methodology for the synthesis of natural products and analogues with improved properties.

Abstract
Heat shock proteins (HSP) are a family of highly conserved proteins, whose expression increases in response to stresses that may threaten cell survival. Over the past decade, heat shock protein 90 (Hsp90) has emerged as a potential therapeutic target for cancer as it plays a vital role in normal cell maturation and acts as a molecular chaperone for proper folding, assembly, and stabilization of many oncogenic proteins. To date, a majority of Hsp90 inhibitors that have been discovered are macrocycles. The relatively rigid conformation provided by the macrocyclic scaffold allows for a selective interaction with a biological target such as Hsp90. This review highlights the discovery and development of nine macrocycles that inhibit the function of Hsp90, detailing their potency and the client proteins affected by Hsp90 inhibition.
