Synergistic-to-additive antileukemic interactions of piperlongumine (PL) and HDAC inhibitor (HDACi) SAHA (Vorinostat) provide a compelling rationale to construct PL-HDACi hybrids, such as 1–58, which recapitulated the synergism between the parental compounds in high-risk and chemoresistant AML cells. Both PL and HDACi components, either in combination or in hybrid molecules, are essential for inducing

A facile and efficient strategy for the synthesis of α,β-unsaturated lactams throughring-closingmetathesis of easily prepared diene amides is being reported here. Reaction conditions were optimized for metathetic cyclization of diene amides to obtain five- to sevenmembered unsubstituted and β-substituted α,β-unsaturated lactams in good to excellent yield.
Design and synthesis of orally bioavailable inhibitors of inducible nitric oxide synthase. Part 1: synthesis and biological evaluation of dihydropyridin-2-imines
Dihydropyridin-2-imines were synthesized and biologicallyevaluated both in vitro and in vivo using a nitric oxide inhibition assay. Compounds 1, 4, 5 and 7-11 exhibited potent activity in the inducible nitric oxide (iNOS) inhibition assay. Of these 5, 6, 9 and 10 showed 5- to 11-fold increases in isoform selectivity. Compounds 1, 5, 9 and 10 showed potent inhibitory activity in the NOx accumulation

lactams via a copper-catalyzed asymmetric 1,4-addition of the corresponding alanes. Moderate to good yields and good to excellent enantioselectivities are achieved by using a combination of the very cheap copper(II) naphthenate and a readily available phosphine amine ligand. The creation of an all-carbon quaternarystereogeniccenter, via Michael addition to a trisubstitutedconjugated lactam, is also
