SB1317 is a novel small molecule potent CDK/JAK2/FLT3 inhibitor. It dose-dependently inhibits signaling pathways downstream of CDKs, JAK2 and FLT3 in cancer cells with the main targets being CDKs. SB1317 is anti-proliferative in a broad range of tumor cell lines, inducing G1 cell cycle arrest and apoptosis. In vivo, SB1317 exhibits favorable pharmacokinetics after oral dosing in xenograft models and accumulates in tumor tissues, inducing an effective blockade of both CDK and STAT signaling. SB1317 induces tumor regression after oral dosing on both daily and intermittent schedules in a murine model of mutant-FLT3 leukemia (MV4-11) and prolongs survival in a disseminated AML model with wild-type FLT3 and JAK2 (HL-60). SB1317 is active in various models of leukemia and provide a rationale for the ongoing clinical evaluation of TG02 in patients with advanced leukemias.

Saxagliptin hydrate is a selective and reversible DPP4 inhibitor. It demonstrates greater specificity for DPP4 than for either the DPP8 or DPP9 enzymes. It reduces the degradation of the incretin hormone glucagon-like peptide-1, thereby enhancing its actions, and is associated with improved β-cell function and suppression of glucagon secretion.
An impurity of Saxagliptin. Saxagliptin is an inhibitor of dipeptidyl peptidase-4 (DPP-4) used as a hypoglycemic drug. It was approved to treat type 2 diabetes.
Sauchinone, coming from the herbs of Saururus chinensis(Lour.) Baill, is a useful adjunctive treatment for bacterial infection. Sauchinone inhibited oxidative stress, as assessed by stainings of 4-hydroxynonenal and nitrotyrosine: these events may have a role in its inhibitory effects on HSCs activation. Sauchinone attenuated CCl4-induced liver fibrosis and TGF-β1-induced HSCs activation, which might be, at least in part, mediated by suppressing autophagy and oxidative stress in HSCs. Sauchinone protects skin keratinocytes through inhibition of extracellular signal-regulated kinase, c-Jun N-terminal kinase, and p38 MAPK signaling via upregulation of oxidative defense enzymes.
Satraplatin, also known as JM216, is a platinum compound that is currently under investigation as one treatment of patients with advanced prostate cancer who have failed previous chemotherapy. It has not yet received approval from the U.S. Food and Drug Administration. First mentioned in the medical literature in 1993, satraplatin is the first orally active platinum-based chemotherapeutic drug; other available platinum analogues-cisplatin, carboplatin, and oxaliplatin-must be given intravenously. It is made available in the United States jointly by Spectrum Pharmaceuticals and GPC Biotech under the name SPERA (Satraplatin Expanded Rapid Access). The drug has also been used in the treatment of lung and ovarian cancers. The proposed mode of action is that the compound binds to the DNA of cancer cells rendering them incapable of dividing.
