A fluorescent histone deacetylase (HDAC) inhibitor for cellular imaging

Fluorescence microscopy studies using 4-morpholinoscriptaid (4MS) demonstrated rapid cellular uptake of this scriptaid analogue into the cytoplasm but no nuclear penetration. As 4MS and scriptaid have the same in vitro activity against HDACs and KASUMI-1 cells; 4MS exemplifies a rational approach to subtly modify ‘profluorogenic’ substrates for intracellular studies.

Synthesis of new praziquantel analogues: Potential candidates for the treatment of schistosomiasis

An efficient synthesis of antischistosomal drug praziquantel and analogues was achieved and the synthetic route designed was to afford structurally diverse analogues for better structure-activity relationship understanding. Total of nineteen PZQ analogues with structural variations at amide, piperazine and aromatic moieties have been synthesized and fully characterized. Among all the new analogues tested for antischistosomal activity, one dimethoxy tetrahydroisoquinoline analogue and two tetrahydro-beta-carboline analogues exhibited moderate activity against adult Schistosoma mansoni. Tetrahydro-beta-carboline analogues showed moderate activity whereas the presence of p-trifluoromethylbenzoyl and p-toluenesulphonyl moieties resulted in complete suppression of antischistosomal activity.

Dynamics of noncovalent supramolecular complexes. NMR study of the rotational barriers in chiral BINAP palladium(II) and platinum(II) bis(phosphane) complexes that resemble the minimal subunits of chiral polygons and polyhedra

In the reaction between 3-picoline, 2-bromo-5-methylpyridine, 2-methylquinoline, 3-methylisoquinoline, and [MCR-(+)-BINAP)][OTf]2 (M = Pd, Pt; BINAP = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl), the nature and the distribution of the products were investigated by various physical and spectroscopic methods. The alpha-substituents on the heteroaryl ring, such as the bromine atom in 2-bromo-5-methylpyridine or the methyl group in 2-methylquinoline, tend to promote the simultaneous formation of mono(heteroaryl)- and bis-(heteroaryl)-containing products. The reaction of the most sterically demanding 2-methylquinoline favors the formation of mono(heteroaryl) complexes exclusively within the limits of NMR detection. Reaction of 3-picoline with the chiral Pd(II) and Pt(II) bis(triflates) results in the formation of diastereomeric, square-planar, cationic complexes, due to the hindered rotation about the metal-nitrogen heteroaryl bond. 1H NMR variable-temperature studies of [M(R-(+)-BINAP)(3-picoline)2][OTf]2 were performed. The activation barriers for the rotation of the beta-picoline ligands around the M-N linkage axis were determined for [Pd-(R-(+)-BINAP)(3-picoline)2][OTf]2 and [Pt(R-(+)-BINAP)(3-picoline)2][OTf]2 by a kinetic line shape analysis of the methyl signals. The Gibbs free energy of activation was found to be 12(¡À0.5) kcal/mol for the Pd complex 15 and 14(¡À0.5) kcal/mol for the Pt complex 16. Ab initio calculations (HF/lanl2dz) of model complexes [dpe]Pd(HN=CH2)22+ and [dpe]Pt(HN= CH2)22+ (dpe = diphosphinoethylene) provided insights into the observed results. The nitrogen-metal pi-sigma-interaction is found to be stronger for the Pt complex, resulting in a higher energy barrier for the rotation around the Pt-N bond compared to the rotation around the Pd-N bond. A comparison is made between the covalent and coordinated Pt(II) complexes, and the similarities and differences of their dynamic behavior are discussed.

Continuous-flow synthesis of biaryls enabled by multistep solid-handling in a lithiation/borylation/Suzuki-Miyaura cross-coupling sequence

Let it flow: An efficient and modular synthesis of biaryls under continuous-flow conditions has been realized by a lithiation/borylation/Suzuki- Miyaura cross-coupling sequence under ambient conditions. Aryl bromides and heteroaromatic precursors can be transformed in the room-temperature lithiation reaction with nBuLi, followed by borylation and Suzuki-Miyaura coupling with the aid of ultrasonic irradiation (see scheme).
