Nitric oxide (NO) releasing poly ADP-ribose polymerase 1 (PARP-1) inhibitors targeted to glutathione S-transferase P1-overexpressing cancer cells

We report the antitumor effects of nitric oxide (NO) releasing derivatives of the PARP-1 inhibitor olaparib (1). Compound 5b was prepared by coupling the carboxyl group of 3b and the free amino group of arylated diazeniumdiolated piperazine 4. Analogue 5a has the same structure except that the F is replaced by H. Compound 13 is the same as 5b except that a Me2N-N(O)=NO- group was added para and ortho to the nitro groups of the dinitrophenyl ring. The resulting prodrugs are activated by glutathione in a reaction accelerated by glutathione S-transferase P1 (GSTP1), an enzyme frequently overexpressed in cancers. This metabolism generates NO plus a PARP-1 inhibitor simultaneously, consuming reducing equivalents, leading to DNA damage concomitant with inhibition of DNA repair, and in the case of 13 inducing cross-linking glutathionylation of proteins. Compounds 5b and 13 reduced the growth rates of A549 human lung adenocarcinoma xenografts with no evidence of systemic toxicity.

The imidazo[2,1-a]isoindole system. A new skeletal basis for antiplasmodial compounds

The in vitro antiplasmodial activity of some dihydrostilbenamides, phtalazinones, imidazo[2,1-a]isoindole and pyrimido[2,1-a]isoindole derivatives related to the natural dihydrostilbenoid isonotholaenic acid is reported. The evaluation was performed on cultures of F32 strain of Plasmodium falciparum and potent representative compounds were also evaluated in the ferriprotoporphyrin IX biomineralization inhibition test (FBIT). Compounds having the imidazo[2,1-a]isoindole skeleton were the most active and one compound of this group resulted to be as potent as chloroquine, but acting through a mechanism different that of the inhibition of heme biomineralization.

Leishmanicidal activity of some stilbenoids and related heterocyclic compounds

We have evaluated the leishmanicidal activity of some natural and semisynthetic dihydrostilbenoids and several compounds of other series of dihydrostilbamides, isoindoles, phthalazinones, imidazoisoindoles and pyrimidoisoindoles. The evaluation was performed in vitro, on cultures of cutaneous, mucocutaneous and visceral strains of Leishmania spp. The most potent and selective compounds of these series were the dihydrostilbene piperidides.

N-Chlorination-induced, oxidative ring contraction of 1,4-dimethoxyphthalazines

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations.
