Originally identified as allelochemicals involved in plant-parasite interactions, more recently, Strigolactones (SLs) have been shown to play multiple key roles in the rhizosphere communication between plants and mycorrhizal fungi. Even more recent is the hormonal role ascribed to SLs which broadens the biological impact of these relatively simple(More)
A series of furazan and furoxan sulfonamides were prepared and studied for their ability to inhibit human carbonic anhydrase (CA, EC isoforms hCA I, hCA II, hCA IX, and hCA XII. The simple methyl substituted products 3-5 were potent inhibitors. Differing structural modifications of these leads had differing effects on potency and selectivity. In(More)
Since the first report and due to its handiness and wide scope, the Suzuki-Miyaura (SM) cross coupling reaction has become a routine methodology in many laboratories worldwide. With respect to other common transition metal catalyzed cross couplings, the SM reaction has been so far less exploited as a tool to introduce an acyl function into a specific(More)
The regioselective benzylic metalation of substituted toluenes using BuLi/KO-t-Bu/TMP(H) (LiNK metalation conditions) with subsequent in situ oxidative C-C coupling has been developed for the facile generation of 1,2-diarylethanes. A range of oxidants can be used for the oxidative coupling step, with 1,2-dibromoethane proving optimal. Heterocouplings can be(More)
A library of nitric oxide-donor doxorubicins (NO-DOXOs) was synthesized by linking appropriate NO-donor moieties at C-14 position through an ester bridge. Their hydrolytic stability was evaluated. The intracellular accumulation and cytotoxicity of these novel NO-DOXOs were studied in DOXO-sensitive (HT29) and DOXO-resistant (HT29/dx) tumor-cells.(More)
The synthesis of bench-stable α,α-bis(trimethylsilyl)toluenes and tris(trimethylsilyl)methane is described and their use in stereoselective Peterson olefinations has been achieved with a wide substrate scope. Product stereoselectivity was poor with carbonyl electrophiles (E/Z ∼1:1 to 4:1) though this was significantly improved by employing the corresponding(More)
Nitric oxide (NO) release from a suitable NO photodonor (NOP) can be fine-tuned by visible light stimuli at doses that are not toxic to cells but that inhibit several efflux pumps; these are mainly responsible for the multidrug resistance of the anticancer agent doxorubicin (DOX). The strategy may thus increase DOX toxicity against resistant cancer cells.(More)
Strigolactones (SLs) are a new class of plant hormones whose role has been recently defined in shoot branching, root development and architecture, and nodulation. They are also active in the rhizosphere as signalling molecules in the communication between plants, AMF (arbuscular mycorrhizal fungi) and parasitic weeds. In spite of the crucial and(More)
Using a facile synthetic route, an organic NO release agent based on a BODIPY light-harvesting antenna was devised. This compound is stable in the dark and delivers NO under photoexcitation with biologically favorable green light. Temporally regulated vasodilation capability is demonstrated on rat aorta by green-light-induced NO release.
