The structural requirements of histone deacetylase inhibitors: C4-modified SAHA analogs display dual HDAC6/HDAC8 selectivity

Histone deacetylase (HDAC) enzymes govern the post-translational acetylation state of lysine residues on protein substrates, leading to regulatory changes in cell function. Due to their role in cancers, HDAC proteins have emerged as promising targets for cancer treatment. Four HDAC inhibitors have been approved as anti-cancer therapeutics, including SAHA (Suberoylanilide hydroxamic acid, Vorinostat, Zolinza). SAHA is a nonselective HDAC inhibitor that targets most of the eleven HDAC isoforms. The nonselectivity of SAHA might account for its clinical side effects, but certainly limits its use as a chemical tool to study cancer-related HDAC cell biology. Herein, the nonselective HDAC inhibitor SAHA was modified at the C4 position of the linker to explore activity and selectivity. Several C4-modified SAHA analogs exhibited dual HDAC6/8 selectivity. Interestingly, (R)-C4-benzyl SAHA displayed 520- to 1300-fold selectivity for HDAC6 and HDAC8 over HDAC1, 2, and 3, with IC50 values of 48 and 27 nM with HDAC6 and 8, respectively. In cellulo testing of the inhibitors was consistent with the observed in vitro selectivity. Docking studies provided a structural rationale for selectivity. The C4-SAHA analogs represent useful chemical tools to understand the role of HDAC6 and HDAC8 in cancer biology and exciting lead compounds for targeting of both HDAC6 and HDAC8 in various cancers.

Controlled-deactivation cannabinergic ligands

We report an approach for obtaining novel cannabinoid analogues with controllable deactivation and improved druggability. Our design involves the incorporation of a metabolically labile ester group at the 2?-position on a series of (-)-Delta8-THC analogues. We have sought to introduce benzylic substituents alpha to the ester group which affect the half-lives of deactivation through enzymatic activity while enhancing the affinities and efficacies of individual ligands for the CB1 and CB2 receptors. The 1?-(S)-methyl, 1?-gem-dimethyl, and 1?-cyclobutyl analogues exhibit remarkably high affinities for both CB receptors. The novel ligands are susceptible to enzymatic hydrolysis by plasma esterases in a controllable manner, while their metabolites are inactive at the CB receptors. In further in vitro and in vivo experiments key analogues were shown to be potent CB1 receptor agonists and to exhibit CB1-mediated hypothermic and analgesic effects.

Enhanced enantiocontrol in catalytic metal carbene transformations with dirhodium(II) tetrakis, Rh2(4S-MEOX)4

The synthesis, spectral characteristics, and X-ray structures for dirhodium(II) tetrakis, Rh2(4S-MEOX)4, and the related dirhodium(II) tetrakis, Rh2(4S-THREOX)4, are reported.Comparison is made between these 2-oxooxazolidin-ligated dirhodium(II) catalysts for metal carbene transformations and those with comparable 2-oxopyrrolidine ligands, especially dirhodium(II) tetrakis, Rh2(5S-MEPY)4.Structure-selectivity comparisons reveal that Rh2(4S-MEOX)4 provides higher enantiocontrol and, in some cases, higher diastereocontrol than Rh2(5S-MEPY)4 in intramolecular carbon-hydrogen insertion reactions of sterically demanding diazoacetates and diazoacetamides and is the catalyst of choice for highly enantioselective diazodecomposition of adamantyl diazoacetates and N-(tert)butyldiazoacetamides.The structurally analogous Rh2(4S-THREOX)4 is nearly identical with Rh2(4S-MEOX)4 in its overall effect on selectivity.The net advantage of Rh2(4S-MEOX)4 lies in its wider openness for metal carbene transformations.

Synthesis of the alkaloid tyroscherin by an aldol/Curtius strategy

The alkaloid tyroscherin (2), which contains a vicinal anti-amino alcohol subunit was prepared from 4-hydroxyphenylpropionic acid (5) and meso-diol 9. After desymmetrization of diol 9 and suitable protecting group manipulations, one terminus was extended via a Claisen rearrangement giving rise to enoate ent-15. The missing carbon on the other end could be incorporated using MeMgCl/CuBr¡¤SMe2 leading eventually to aldehyde ent-22. The acylated oxazolidinone 32 derived from acid 5 and aldehyde ent-22 were combined in an aldol reaction. A subsequent Curtius rearrangement on the carboxylic group furnished the amino function of tyroscherin (2). In a proof of concept study the same strategy was used to prepare tyroscherin analog 28.

Design, synthesis and biological evaluation of substituted (+)-SG-1 derivatives as novel anti-HIV agents

SG-1 was previously identified as a potent Non-nucleoside reverse transcriptase inhibitors (NNRTI) which works through inhibition of reverse transcriptase (RT) RNA-dependent DNA polymerase activity via a direct binding event. To further investigate the relationship between its structure and activity, four series of novel analogues were designed and synthesized with 12 of them inhibiting HIV-1 replication with IC50s in the range 0.09?6.71 muM. Compound 4b, 4c, 4f, 2 and 6b were further tested on two NNRTI-resistant HIV-1 strains and one NNRTI-resistant superbug. The result showed that RT- E138K/M184V mutant virus conferred 4.7?9.1-fold resistance to 4c, 4f, 2 and 6b, but only showed slight resistance to 4b (2-fold) which was better than SG-1.

Convenient and practical alkynylation of heteronucleophiles with copper acetylides

Copper acetylides, readily available reagents which are characterized by their lack of reactivity, can be simply activated by oxidation with oxygen in the presence of simple nitrogen ligands such as TMEDA or imidazole derivatives. Upon activation, these nucleophilic species undergo a formal umpolung and can transfer their alkyne subunit to a wide range of heteronucleophiles, including amides, oxazolidinones, imines, and dialkyl phosphites. This alkynylation, which provides one of the most practical entry to useful building blocks such as ynamides, ynimines, and alkynylphosphonates, proceeds under especially mild conditions and can be easily performed on a multigram scale.
