Currently in Phase I clinical study for the treatment of solid tumors Both are quinoxaline derivatives as evidenced A66 by their recently unveiled leaked structures63. GDC0941 is a derivative of the PI 103, which . It seems t potent antitumor activity t in pr Xenograft and clinical Phase I has tra dinner in patients with solid tumors or lymphomas. GSK1059615, additional clinical candidates targeting PI3K, has recently concluded clinical trials in patients with solid tumors or lymphomas. SF1126 is a covalent conjugate of LY294002 with a RGD peptide con U to the L Solubility and better performance of the active drug to the tumor increased to 69 Hen.
In pr Clinical studies, SF1126 has been shown that strong inhibitory effect on cell growth, proliferation and angiogenesis with reduced toxicity t Compared to LY294002 parent. SF1126 has entered a Phase I clinical trial as a PI3K/mTOR inhibitor in a wide range of cancers with solid tumors. A number of compounds, which preferably Selected hlt Isoforms of class I PI3Ks specifically also in development. For example, PX 866 target P110, P110 and P110 with single-digit nanomolar IC50 ? ? 70, w While CAL 101 is a selective inhibitor of p110 ? under Phase I clinical trial in patients with relapsed or refractory Malignant Ren h dermatological diseases. AKT downstream target the most critical nodes proximal RTK/PI3K is complex, AKT is another therapeutic target.
A large number of e AKT inhibitors have been developed, the confinement in a number of classes, Lich lipid-based analogues phosphatidylinositol, ATP competitive inhibitors and allosteric inhibitors are grouped. The inhibitor advanced clinically, perifosine, a lipid analog IP-based targeting the PH Dom ne of AKT, thereby 71st binding to PIP3 and thus its membrane translocation It is currently in clinical trials as monotherapy or in combination with different drugs to treat various types of cancer. Other inhibitors AKT PH Cathedral ne, Including normal PX316 72 and PIA activity74 showed inhibitory effects on the growth of tumor cells with high PI3K / Akt. Most ATP wettbewerbsf HIGEN small molecule inhibitors are non-selective ACT, the ACT to all three isoforms. GSK690693 ATP is a competitive inhibitor of AKT kinase, which provides for all three isoforms with low nanomolar AKT and is also active against other kinases family75 AGC kinase.
A big problem in terms of the m Resembled advantages the specific isoform facing a number of allosteric AKT inhibitors recently by screening libraries of compounds and the use of an iterative analogue synthetic library have been identified. This allosteric AKT inhibitors have demonstrated a certain degree of selectivity t isoform. Akti 1/2, an allosteric inhibitor AKT1 and AKT2 naphthyridinone twice, showed strong anti-tumor activity t in xenograft models of tumors and MK2206 analogue phase I trial in patients with locally advanced or metastatic solid tumors. XL418, a small molecule, the activity of the t Of AKT and S6K inhibits antineoplastic activity of t In pr Clinical trials, is in Phase I clinical trials in patients with advanced solid tumors.
