  Syntheses and in Vitro Antiplasmodial Activity of Aminoalkylated Chalcones and Analogues

  摘要：

  A series of readily synthesized and inexpensive aminoalkylated chalcones and diarylpropane analogues (1-55) were synthesized and tested against chloroquinone-sensitive (D10 and NF54) and -resistant (Dd2 and K1) strains of Plasmodium falciparum. Hydrogenation of the enone to a diarylpropane moiety increased antiplasmodial bioactivity significantly. The influence of the structure of the amine moiety, A-ring substituents, propyl vs ethyl linker, and chloride salt formation on further enhancing antiplasmodial activity was investigated. Several compounds have IC50 values similar to or better than chloroquine (CQ). The most active compound (26) had an IC50 value of 0.01 mu M. No signs of resistance were detected, as can be expected from compounds with structures unrelated to CQ and other currently used antimalarial drugs. Toxicity tests (in vitro CHO cell assay) gave high SI indices.

• Thiophene and furan appended pyrazoline based fluorescent chemosensors for detection of Al3+ ion
  作者：Manjunath Rangasamy、Kannan Palaninathan

  Thiophene and furan appended pyrazoline receptors R1 and R2 were designed and synthesized for selective detection of Al3+ ion. Their photophysical properties were studied by UV-visible and fluorescence spectra. Surprisingly, both receptors R1 and R2 were displayed an excellent selective and sensitive response to Al3+ ion alone over other tested metal ions. Both the receptor R1 and R2 displays 1:1 stoichiometry for [R1-Al3+] and [R2-Al3+] complex and formed with an association constant of 1.84 x 10(4) M-1 and 1.92 x 10(4) M-1 respectively. The limit of detection were calculated for R1 and R2 since 8.92 x 10(-8) M and 1.04 x 10(-7) M by the fluorescence titration method. The thiophene based receptor R1 exhibited superior chemosensor characteristics such as high intensity absorption and emission at longer wavelength as compered that of furan based receptor R2.
