IKD-8344 is a macrocyclic dilactone originally isolated from an actinomycete species and has diverse biological activities, including anticancer, antimicrobial, and anthelmintic properties.1,2,3 It is cytotoxic to L5178Y murine leukemia cells (IC50 = 0.54 ng/ml).1 IKD-8344 inhibits growth of the mycelial form of C. albicans (MIC = 6.25 μg/ml) and potentiates the activity of polymyxin B against the multidrug-resistant pathogenic bacterium B. cenocepacia.2,3 It is active against T. spiralis in vitro and in vivo.1

Three rings in one step: a quick approach to IKD-8344
Angew Chem Int Ed Engl 2012 May 14;51(20):4968-71.PMID:22492554DOI:10.1002/anie.201201395.
A highly efficient enantioselective total synthesis of the natural antibiotic IKD-8344 is achieved through a convergent route. This route features an otherwise impossible concurrent formation of the THF rings from a linear polyketide precursor through intramolecular O alkylations of mesylates in competition with normally rather facile β elimination and/or α racemization reactions (see scheme, Ms=methanesulfonyl).
Synthesis of enantiopure termini-differentiated heptane stereotriads. Application to side chain-functionalized tetrahydrofurans of IKD-8344
Org Lett 2000 Jul 27;2(15):2181-4.PMID:10930238DOI:10.1021/ol005791o.
Enantiopure epoxy cycloheptenyl sulfones syn-7b and anti-7b are prepared in five high-yielding and stereospecific operations from 1, 3-cycloheptadiene. These substrates serve as effective precursors for cis- and trans-substituted tetrahydrofurans (12, 10) which are segments of the antineoplastic agent IKD-8344.
