Discovery of potent HIV integrase inhibitors active against raltegravir resistant viruses

A series of novel HIV integrase inhibitors active against rategravir resistant strains are reported. Initial SAR studies revealed that activities against wild-type virus were successfully maintained at single digit nanomolar level with a wide range of substitutions. However, inclusion of nitrogen-based cyclic substitutions was crucial for achieving potency against mutant viruses. Several compounds with excellent activities against wild-type virus as well as against the viruses with the mutations Q148H/G140S or N155H/E92Q were reported.

New asymmetric synthesis of protein farnesyltransferase inhibitors via palladium-catalyzed cross-coupling reactions of 2-iodo-imidazoles

Palladium catalyzed cross-coupling reactions of 2-iodoimidazole have been studied to synthesize imidazole-containing protein farnesyltransferase inhibitors. The Suzuki coupling reaction proved to be very efficient to introduce functionalized alkyl chains at the 2-position of the imidazole ring and a new synthesis of the required alkenylboronates was realised by a reaction of cross metathesis. Asymmetric synthesis of allyl succinic derivatives allowed us to synthesize chiral protein farnesyltransferase inhibitors through Suzuki coupling and to determine the influence of the stereochemistry of our inhibitors on the enzymatic activity.

Synthesis and biological activity of enantiomeric pairs of 5-vinylthiolactomycin congeners

Twelve enantiomeric pairs of 5-vinylthiolactomycin congeners were synthesized by employing our efficient synthetic route previously explored for the synthesis of enantiomeric pairs of thiolactomycin and its 3-demethyl derivative. From the biological activity assay carried out using the obtained congeners along with enantiomeric pairs of thiolactomycin and its 3-demethyl derivative previously prepared, it appeared evident that in vitro antibacterial and mammalian type I FAS inhibitory activity of thiolactomycin congeners can be cleanly separated by changing not only the structure but also the absolute configuration of the side chain at the C5-position. These studies led us to explore (S)-3-demethyl-5-(pent-1-enyl)thiolactomycin derivative [(S)-4-hydroxy-5-methyl-5-(pent-1-enyl)-5H-thiophen-2-one] which exhibits type I FAS inhibitory activity equal to that of C75, the potent inhibitor so far reported, with complete loss of in vitro antibacterial activity.

Total synthesis of a hemiacetal polypropionate from Siphonaria australis

A highly stereocontrolled synthesis of (2S,3R,5R,6S)-6-[(1E,3R)-1,3- dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3,5-dimethyltetrahydro-4H-pyran-4-one has been achieved in 13 steps and an overall yield of 7.6% from (A)-(+)-4- benzyloxazolidin-2-one. This substrate-controlled asymmetric synthesis utilized Paterson’s lactate-derived chiral ketone (2S)-2-(benzoyloxy) pentan-3-one to generate the 5R and 6S stereocentres and alkylation of an Evans’ auxiliary to generate the remote side-chain 3R stereocentre. Furthermore, a novel, highly efficient, and selective strategy was used to generate an enol trimethylsilyl ether whose subsequent Mukaiyama aldol condensation gave the acyclic precursor to the final product. A thermodynamically controlled cyclization then gave (2S,3R,5R,6S)-6-[(1E,3R)-1,3-dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3, 5-dimethyltetrahydro-4H-pyran-4-one with control of the 2S and 3R stereocentres. The NMR spectroscopic data and optical rotation obtained for synthetic (2S,3R,5R,6S)-6-[(1E,3R)-1,3-dimethylhex-1-enyl]-2-ethyl-2-hydroxy-3, 5-dimethyltetrahydro-4H-pyran-4-one were consistent with those reported forthe hemiacetal isolated from Siphonaria australis, and thus, prove the absolute and relative configuration of the natural product.

Total synthesis of the Tiacumicin B (lipiarmycin A3/fidaxomicin) aglycone

Tiacumicin B (lipiarmycin A3, fidaxomicin) is an atypical macrolide antibiotic which is used for the treatment of Clostridium difficile infections. Tiacumicin B is also a potent inhibitor of Mycobacterium tuberculosis, but due to its limited oral bioavailability is unsuitable for systemic therapy. To provide a basis for structure-activity studies that might eventually lead to improved variants of tiacumicin B, we have developed an efficient approach to the synthesis of the tiacumicin B aglycone. The synthesis features a high-yielding intramolecular Suzuki cross-coupling reaction to effect macrocyclic ring closure. Key steps in the synthesis of the macrocyclization precursor were a highly selective, one-pot Corey-Peterson olefination and an ene-diene cross-metathesis reaction. Depending on the reaction conditions, the final deprotection delivered either the fully deprotected tiacumicin B aglycone or partially protected versions thereof.
