Importance of metal complexes for development of potential leishmanicidal agents

The occurrence of adverse effects and the development of resistance associated with the administration of conventional anti-leishmanial drugs explicate the urgent need for development of new leishmanicidal agents. The potential use of metal complexes as drugs against parasitic diseases has so far been very little explored. Leishmaniasis affects millions of people around the world with very limited therapeutic options for their treatment. This review focuses on the recent advances in the development of complex anti-leishmania agents.

Catalytic, metal-free sulfonylcyanation of alkenes: Via visible light organophotoredox catalysis

The group transfer radical addition of olefins with tosyl cyanide has been accomplished via visible light-induced organophotoredox catalysis. A diverse array of olefins is amenable to this protocol, furnishing beta-sulfonyl nitriles with excellent efficiency under metal-free and redox-neutral conditions. A closed catalytic cycle is operative in this transformation, providing complementary reactivity to the classic radical chain process.

Photosensitized oxidations of substituted pyrroles: Unanticipated radical-derived oxygenated products

(Chemical Equation Presented) Photooxidation of pyrrole adducts 7-10 has been investigated in order to establish a general reaction pattern andmechanism for the formation of the resulting oxygenated products. The reactions were performed in several solvents utilizing both type I and type II sensitizers. In most cases, photooxidations gave complex mixture of products. Among these products, 5,5- or 6,5-bicyclic lactams (11, 15, and 19), maleimide 12 unsaturated gamma-lactams (16 and 20), 5-hydroxylactams (13, 17, and21), and 5-methoxylactams (14, 18, and22) wereisolated and characterized. Photooxidation of 2,5-dimethyl-substituted pyrrole 10 in aprotic solvents unexpectedly afforded aldehyde 23 as the major product. Moreover, photooxidation of pyrrole adduct 10 in protic solvents exclusively gave the unprecedented solvent-trapped products 24-27. The formation of products 11-22 was rationalized by the intermediacy of a commonendoperoxide intermediate, whichcould be formedby both type I and type II mechanisms. Compounds 23-27 were most probably formed via an electron-transfer mechanism. 2009 American Chemical Society.

Discovery of a series of 8-(1-phenylpyrrolidin-2-yl)-6-carboxamide-2-morpholino-4H-chromen-4-one as PI3Kbeta/delta inhibitors for the treatment of PTEN-deficient tumours

Attempts to lock the active conformation of compound 4, a PI3Kbeta/delta inhibitor (PI3Kbeta cell IC50 0.015?muM), led to the discovery of a series of 8-(1-phenylpyrrolidin-2-yl)-6-carboxamide-2-morpholino-4H-chromen-4-ones, which showed high levels of potency and selectivity as PI3Kbeta/delta inhibitors. Compound 10 proved exquisitely potent and selective: PI3Kbeta cell IC50 0.0011?muM in PTEN null MDA-MB-468 cell and PI3Kdelta cell IC50 0.014?muM in Jeko-1 B-cell, and exhibited suitable physical properties for oral administration. In vivo, compound 10 showed profound pharmacodynamic modulation of AKT phosphorylation in a mouse PTEN-null PC3 prostate tumour xenograft after a single oral dose and gave excellent tumour growth inhibition in the same model after chronic oral dosing. Based on these results, compound 10 was selected as one of our PI3Kbeta/delta preclinical candidates.

Influence of the A-ring on the proton affinity and anticancer properties of the prodigiosins

Prodigiosin (Prod, 1) is the parent member of a class of polypyrrole natural products that exhibit promising immunosuppressive and anticancer activities. They are known to act as H+/Cl- symporters possibly through electrostatic binding to Cl- that facilitates proton-coupled transmembrane transport of halides. This activity has been ascribed to their promotion of apoptosis by acidification of the intracellular pH (pHi). Since the protonated pyrromethene chromophore of Prod (1) is expected to play a critical role in pHi regulation, and the A-pyrrole ring is known to be important for anticancer activity, we prepared several Prod analogues with various A-ring systems to determine their proton affinity in 1:1 (v/v) acetonitrile (MeCN)/H2O and anticancer properties against HL-60 cancer cells. Our studies show that the A-ring strongly influences the proton affinity of the pyrromethene entity. Replacement of the C-2 methoxy group in 2,4-dimethoxy-pyrromethene 3 (apparent pKa = 4.95) with the A-pyrrole ring to generate the Prod analogue 5 raised the apparent pKa to 7.54 (increase by 2.59 pK units) and caused a 76 nm red shift in the UV-vis absorbance of the protonated species (AH+). The A-pyrrole NH atom plays an important role in stabilization of AH+, as its replacement with O or S atoms decreases the apparent pKa by 0.79 and 1.07 pK units, respectively. A 4-substituted phenyl series of Prod analogues 8-14 exhibited a linear correlation with the Hammett sigmap values. Within the phenyl series, two Prod analogues were found to inhibit colony formation of HL-60 cancer cells, although the inhibition did not correlate with the proton affinity of the pyrromethene entity. The implications of these findings with regard to the anticancer activities of the prodigiosins are discussed.

Catalytic intermolecular hydroaminations of unactivated olefins with secondary alkyl amines

The intermolecular hydroamination of unactivated alkenes with simple dialkyl amines remains an unsolved problem in organic synthesis. We report a catalytic protocol for efficient additions of cyclic and acyclic secondary alkyl amines to a wide range of alkyl olefins with complete anti-Markovnikov regioselectivity. In this process, carbon-nitrogen bond formation proceeds through a key aminium radical cation intermediate that is generated via electron transfer between an excited-state iridium photocatalyst and an amine substrate. These reactions are redox-neutral and completely atom-economical, exhibit broad functional group tolerance, and occur readily at room temperature under visible light irradiation. Certain tertiary amine products generated through this method are formally endergonic relative to their constituent olefin and amine starting materials and thus are not accessible via direct coupling with conventional ground-state catalysts.
