  • Patent number: 9561237
    Abstract: Platinum(II) complexes having mixed ligands as anticancer agents. The central platinum atom is coordinated by two phosphine ligands and two heterocyclic thione ligands. Each heterocyclic thione ligand has a five-, six- or seven-membered heterocyclic ring with two nitrogen atoms at positions 1 and 3 of the ring and a thiocarbonyl group at position 2. Pharmaceutical compositions incorporated the platinum(II) complexes, methods of synthesizing the complexes and methods of treating cancers with the complexes or pharmaceutical compositions thereof are also described.

  • Publication number: 20170020901
    Abstract: Gold(I) complexes of formulae [Au{P(t-Bu)3}(S2CN(CH3)2)] (1), and [Au{P(t-Bu)3}(S2CN(C2H5)2)] (2) have been prepared by the reaction of equimolar amounts of [Au{P(t-Bu)3}(Cl)] with sodium dimethyldithiocarbamate monohydrate, and sodium diethyldithiocarbamate trihydrate respectively. Both complexes (1) and (2) are iso-structural having linear geometry. These gold(I) dithiocarbamate complexes show in vitro cytotoxic activities against A549 (human lung carcinoma), HeLa (human cervical cancer) and MCF7 (human breast cancer) cell lines.

  • Patent number: 9487542
    Abstract: Gold(III) complexes having mixed ligands as anticancer agents. The atom is coordinated by bidentate ligands having diamino functional groups: a diaminocyclohexane ligand and an ethylenediamine ligand. These complexes can exist in both cis- and trans-configurations. Also described are pharmaceutical compositions incorporating the gold(III) complexes, methods of synthesis, methods of treating cancer and methods of inhibiting cancer cell proliferation and inducing cancer cell apoptosis.

  • Patent number: 9481693
    Abstract: Gold(III) complexes with mixed ligands as anticancer agents. The gold(III) cations are coordinated to bidentate ligands having diamino functional groups: a diaminocyclohexane ligand and a 1,3-propylenediamine ligand. The diaminocyclohexane ligand can exist in both cis- and trans-configurations, resulting in isomeric gold(III) complexes. Also described are pharmaceutical compositions incorporating the gold(III) complexes, methods of synthesis, methods of treating cancer and methods of inhibiting cancer cell proliferation and inducing cancer cell apoptosis.

  • Publication number: 20160249846
    Abstract: A SoC includes an AFE to receive a plurality of differential input channels and generate digitized data corresponding to the channels, and a classification processor configured to receive the digitized data from the AFE. The AFE includes a Dual-Channel Chopper to perform channel multiplexing of two channels while simultaneously chopping the channels, a Dual Channel Charge Recycled-AFE having an Chopper-Stabilized Capacitive-Coupled IA including bias sampling capacitors that store bias values associated with the first and second channels to enable swapping between the channel, and a DC servo loop (DSL) having a reduced setting time based on a reduction in a resistance of the pseudo-PMOS in response to engaging a system reset. The classification processor includes a Frequency-Time Division Multiplexing (FTDM) Feature Extraction (FE) engine and a Dual-Detector Architecture (D2A) classification processor.
