SRT2104, also known as GSK2245840, is a novel, first in class, highly selective small molecule activator of the NAD + dependent deacetylase SIRT1. SIRT1 has been suggested as putative therapeutic target in multiple age-related diseases including type 2 diabetes and dyslipidemias. SRT2104 in the phase II of clinical trial to treat type 2 diabetes mellitus and psoriasis also in the phase I for its use in case of colitis. Also was reported, that we report that SRT2104, penetrated the blood-brain barrier, attenuated brain atrophy, improved motor function, and extended survival in a mouse model of Huntington's disease.

T-900607 is a pentafluorophenylsulphonamide derivative patented by Tularik Inc. as antiproliferative agent. Antitumor mechanism of T900607 is similar to the vinca alkaloids in terms of disruption of microtubule polymerization but uniquely causes a specific covalent modification of β-tubulin. In preclinical studies, T900607 was shown to bind irreversibly and specifically to the β1, β2, and β4 isotypes of β-tubulin is not a substrate for p-glycoprotein drug pump and has activity in the preclinical setting in MDR models. T900607 was evaluated in human tumor xenografts and showed activity in MX-1, MCF-7, and MCF-7/ADR mammary, C13 ovarian, HT 29 colon, and Caki-1 renal carcinoma as well as lymphoblastic leukemia, with equal or more efficacious effects compared to vinblastine, doxorubicin and paclitaxel. In a clinical trial, T-900607 shows significant toxicity, consisting of thrombocytopenia, nausea/vomiting, fatigue, and apparent cardiac toxicity.

Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile) is an organic compound mainly used as a broad spectrum, nonsystemic fungicide, with other uses as a wood protectant, pesticide, acaricide, and to control mold, mildew, bacteria, algae. Chlorothalonil reduces fungal intracellular glutathione molecules to alternate forms which cannot participate in essential enzymatic reactions, ultimately leading to cell death. Chlorothalonil is slightly toxic to mammals, but it can cause severe eye and skin irritation in certain formulations. Very high doses may cause a loss of muscle coordination, rapid breathing, nose bleeding, vomiting, and hyperactivity. Dermatitis, vaginal bleeding, bright yellow and/or bloody urine, and kidney tumors may also occur, followed by death. In a number of tests of varying lengths of time, rats which were fed a range of doses of chlorothalonil generally showed no effects on physical appearance, behavior, or survival. Kidney changes such as kidney enlargement were common. In the US, chlorothalonil is used predominantly on peanuts (about 34% of usage), potatoes (about 12%), and tomatoes (about 7%), though the EPA recognizes its use on many other crops. It is also used on golf courses and lawns (about 10%) and as a preservative additive in some paints (about 13%), resins, emulsions, and coatings. Chlorothalonil is commercially available in many different formulations and delivery methods. It is applied as a dust, dry or water-soluble grains, a wettable powder, a liquid spray, a fog, and a dip. It may be applied by hand, by ground sprayer, or by aircraft

ZSTK474 is a new PI3K inhibitor with strong antitumor activity against human cancer xenografts without toxic effects in critical organs. Specifically, ZSTK474 is an ATP-competitive inhibitor of class I phosphatidylinositol 3 kinase isoforms. ZSTK474 blocks VEGF-induced cell migration and the tube formation in human umbilical vein endothelial cells (HUVECs), and inhibits the expression of HIF-1α and secretion of VEGF in RXF-631L cells, exhibiting potent in vitro antiangiogenic activity. ZSTK474 demonstrated prophylactic efficacy in a rat model of rheumatoid arthritis (RA) through inhibition of T cell and FLS functions.
