cyclohexenone/neoplasms

Herein we report the synthesis, photophysical properties, positron emission tomography (PET) imaging and photodynamic therapy (PDT) efficacy of methyl 3-(1'-m-iodobenzyloxy)ethyl-3-devinyl-verdin 4 (with or without the ¹²⁴ I isotope). The PET imaging ability and ex vivo biodistribution of

Bioactivity-guided fractionation of the ethyl acetate extract of the leaves of Poupartia borbonica led to the isolation of three new alkyl cyclohexenone derivatives 1-3, and named Poupartone A-C. The structures of the new compounds were elucidated by 1D and 2D NMR spectroscopic data analysis and MS,

A series of structurally simplified cryptocaryone analogues were synthesized by a facile Pd-catalyzed acetoxylation of alkyne-tethered cyclohexadienones and evaluated as inhibitors of NF-κB signaling. Compounds 10 and 11 were found to possess low micromolar inhibitory properties towards induced

Two new cyclohexenones (antheminones A and B) and a new cyclohexanone, (antheminone C) along with five known compounds were isolated from the leaves of Anthemis maritima L. The structures were mainly deduced from extensive 1D and 2D NMR spectroscopy and mass spectrometry. The new compounds were

Two novel natural products, lanneaquinol (1) and 2'(R)-hydroxylanneaquinol (2), were isolated from the organic extract of the plant Lannea welwitschii (Hiern) Engl. Their structures were solved by spectroanalytical methods and confirmed by comparison to synthetic models. The absolute configuration

The antitumor activity of 2-crotonyloxymethyl-2-cyclohexenone (COMC-6) is not the result of the GSH conjugate (GSMC-6) formed inside tumor cells, as the diethyl ester prodrug form of GSMC-6 displays little antitumor activity with B16 melanotic melanoma in vitro (IC(50) > 460 microM) versus COMC-6

Syntheses are described for and structure:activity studies undertaken of the anti-tumour activity of (2-crotonyloxymethyl-(4R,5R,6R)-4,5,6-trihydroxycyclohex-2-+ ++enone) (1) and its analogues 1-crotonyloxymethyl-(3R,4S,5R)-3,4,5-trihydroxycyclohex-1-en e (3),

Human glutathione (GSH) transferase (hGSTP1-1) processes with similar kinetic efficiencies the antitumor agents 2-crotonyloxymethyl-2-cyclohexenone (COMC-6), 2-crotonyloxymethyl-2-cycloheptenone (COMC-7), and 2-crotonyloxymethyl-2-cyclopentenone (COMC-5) to 2-glutathionylmethyl-2-cyclohexenone,

Two new cyclohexene derivatives colletotricones A and B (1 and 2) and a new thiazole derivative colletotricole A (5), along with six known natural metabolites were isolated from the extract of Colletotrichum gloeosporioides A12, an endophytic fungus derived from Aquilaria sinensis. Among them, the

New target compounds were designed as inhibitors of tubulin polymerization relying on using two types of ring B models (cyclohexenone and indazole) to replace the central ring in colchicine. Different functional groups (R1) were attached to manipulate their physicochemical properties and/or their

The incorporation of anticancer prodrugs into polyacrylamide conjugates has been shown to improve tumor targeting via the so-called "enhanced permeability and retention" effect. This strategy has now been expanded to include two different classes of glutathione (GSH)-activated antitumor agents
