octane/neoplasms

Paclitaxel is one of the most important anti-cancer agents introduced during the last 20 years. However, the use of paclitaxel is limited by undesirable side effects as well as the development of drug resistance. Here, we report a synthetic strategy towards spiro-bicyclo[2.2.2]octane derivatives,

The relatively broad and overlapping specificities of amino acid transport systems have made the synthesis of analogues specific to single transport systems desirable. The analogue in general use as a specific substrate for transport system L has been 2-aminobicyclo[2.2.1]heptane-2-carboxylic acid

1,4‑Naphthoquinone derivatives have superior anticancer effects, but their use has been severely limited in clinical practice due to adverse side effects. To reduce the side effects and extend the anticancer effects of 1,4‑naphthoquinone derivatives, 2‑(butane‑1‑sulfinyl)‑1,4‑naphthoquinone (BQ) and

We report on encapsulation of cyanine IR-768 in oil-in-water (o/w) microemulsion, i.e. fabrication of templated polymeric nanocapsules as effective nanocarriers for a new generation of photodynamic agents suitable for photodynamic therapy (PDT). Discussed here are nanocapsule imaging, their in vitro

2-(Allylthio)pyrazine derivatives were designed as a novel cancer chemopreventive agent that functions through selective inhibtion of cytochrome P-450 and induction of phase II enzymes involved in the detoxification of carcinogens. A practical preparation method of 2-(allylthio) pyrazine derivatives

Methyl tertiary butyl ether (MTBE) is an additive in some formulations of unleaded gasoline (UG) that enhances octane and reduces carbon monoxide emissions from motor vehicles. MTBE in CD-1 mice and UG in B6C3F1 mice increased the incidence of liver tumors selectively in female mice in their chronic

Dual action alkyl(aryl)amino-1,3,5-triazines functionalized with nitrogen mustards were obtained by treating 2-alkyl(aryl) amino-4-chloro-6-methoxy-1,3,5-triazines with amines or amino acid methyl esters, followed by reactions with 1,4-diazabicyclo[2.2.2]octane (DABCO) and rearrangement with an

Our previous study shows that 6-O-acyl derivatives of L-ascorbic acid inhibits more markedly cell growth of mouse Ehrlich carcinoma than ascorbic acid. The present study shows that 6-O-palmitoyl ascorbic acid but not ascorbic acid prolongs the lifespan of mice into which tumors such as Meth A

The role of reactive oxygen (RO) in the promotion of neoplastic transformation of JB6 mouse epidermal cells by 12-O-tetradecanoylphorbol-13-acetate (TPA) was investigated using inhibitors of RO itself or RO generating systems of seven different types. Bovine erythrocyte CuZn superoxide dismutase

OBJECTIVE The purpose of this research was to characterize the pharmacokinetic parameters and to evaluate the absolute bioavailability of the targeted compound: Z-(+/-)-2-(1-benzylindole-3-yl-methylene)azabicyclo[2.2.2]octane-3-ol (BMABO), a novel radio-sensitization agent, after oral

In this work, 23 new amides (14-36) bearing a representative diterpenoid structure unit, the functionalized bicyclo[3.2.1]octane ring, have been synthesized and its antitumor potential is studied. In vitro studies demonstrate that a number of amides with the bicyclo[3.2.1]oct-3-en-2-one subunit are

Highly diastereoselective synthesis of chromeno β-lactam hybrids was achieved by an efficient one-pot three-component reaction. With this procedure, the desired β-lactam products were obtained in good yields and with exclusive cis stereoselection, by combining a variety of benzaldehydes,

This work tested antioxidant, anti-lung cancer, and antibacterial activities by in vitro, in vivo, and computational experiments for the metabolites extracted from the bark, seed, and stem of Toxicodendron vernicifluum. The results showed that all the extracts significantly scavenged

A series of new azaspiro bicyclic hydantoin derivatives has been designed and synthesized. Initially, the anti-proliferative effect of the hydantoin derivatives was evaluated against human ovarian cancer cells (SKOV-3 and OVSAHO) and murine osteosarcoma cells (LM8 and LM8G7). Among the tested

Copper-cysteamine (Cu-Cy) is a novel sensitizer that can be excited by ultraviolet (UV) light, microwave (MW), ultrasound, and X-rays to generate highly toxic reactive oxygen species (ROS) for cancer cell destruction. The purpose of this study is to present a facile method for the synthesis of Cu-Cy
