A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-containing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRP1-overexpressed cell line (2008/MRP1) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRP1- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRP1 and BCRP transporters. The EC_(50 )values for reversing paclitaxel resistance (141-340 nM) of LCC6MDR cells, DOX (78-590 nM) and vincristine (82-550 nM) resistance of 2008/MRP1 cells and topotecan resistance (0.9-135 nM) of HEK293/R2 and MCF7-MX100 cells were at nanomolar range. Importantly, a number of compounds displayed EC_(50 )at or below 10 nM in BCRP-overexpressed cell lines, indicating that these bivalent triazoles more selectively inhibit BCRP transporter than the P-gp and MRP1 transporters. Most of the dimers are notably safe MDR chemosensitizers as indicated by their high therapeutic index values.

Organic thin-film transistors (OTFTs) show promising applications in various chemical and biological sensors. The advantages of OTFT-based sensors include high sensitivity, low cost, easy fabrication, flexibility and biocompatibility. In this paper, we review the chemical sensors and biosensors based on two types of OTFTs, including organic field-effect transistors (OFETs) and organic electrochemical transistors (OECTs), mainly focusing on the papers published in the past 10 years. Various types of OTFT-based sensors, including pH, ion, glucose, DNA, enzyme, antibody-antigen, cell-based sensors, dopamine sensor, etc., are classified and described in the paper in sequence. The sensing mechanisms and the detection limits of the devices are described in details. It is expected that OTFTs may have more important applications in chemical and biological sensing with the development of organic electronics.

Designing mobiles to harvest ambient energy such as kinetic activities or electromagnetic radiation will enable wireless networks to be self-sustaining. In this paper, the spatial throughput of a mobile ad hoc network powered by energy harvesting is analyzed using a stochastic-geometry model. In this model, transmitters are distributed as a Poisson point process and energy arrives at each transmitter randomly with a uniform average rate called the energy arrival rate. Upon harvesting sufficient energy, each transmitter transmits with fixed power to an intended receiver under an outage-probability constraint for a target signal-to-interference-and-noise ratio. It is assumed that transmitters store energy in batteries with infinite capacity. By applying the random-walk theory, the probability that a transmitter transmits, called the transmission probability, is proved to be equal to the smaller of one and the ratio between the energy-arrival rate and transmission power. This result and tools from stochastic geometry are applied to maximize the network throughput for a given energy-arrival rate by optimizing transmission power. The maximum network throughput is shown to be proportional to the optimal transmission probability, which is equal to one if the transmitter density is below a derived function of the energy-arrival rate or otherwise is smaller than one and solves a given polynomial equation. Last, the limits of the maximum network throughput are obtained for the extreme cases of high energy-arrival rates and sparse/dense networks. © 1963-2012 IEEE.
