  Synthesis and evaluation of 4-alkylanilines as mammary tumor inhibiting aromatase inhibitors

  摘要：

  The 4-alkylanilines 1-20 were synthesized to elucidate the importance of the glutarimide moiety for the aromatase inhibiting activity of aminoglutethimide [3-(4-aminophenyl)-3-ethylpiperidine-2,6-dione, AG], the only non-steroidal aromatase inhibitor which is commercially available at present. The most interesting compounds were the (4-aminophenyl)cycloalkanes 4-6 (4, c-pentyl; 5, c-hexyl; 6, c-heptyl) and the 1-alkyl-1-(4-aminophenyl)cyclohexanes 1-3 (1, CH3; 2, C2H5; 3, n-C3H7). Derivatives 1-6 are stronger inhibitors of human placental aromatase than AG exhibiting relative potencies from 1.5 to 2.7 (AG=1). For selectivity of action, the inhibition of desmolase (cholesterol side chain cleavage enzyme) was determined. Compounds 1-3 showed an inhibition comparable to AG, whereas compounds 4-6 exhibited no effect on desmolase. Being more potent and selective aromatase inhibitors in vitro, compounds 4-6, however, were not superior to AG in vivo, when the reduction of plasma estradiol concentration and the tumor inhibiting activity (PMSG-primed SD rats and DMBA-induced mammary carcinoma of the SD rat, postmenopausal model) were concerned.

  A composition for use in liquid crystal display devices, consisting essentially of a nematic liquid crystal material and a helichromic compound possessing both a chromophoric moiety and a helical ordering moiety. The helical ordering moiety is capable of helically ordering the mixture of liquid crystal material and helichromic compound. The helichromic compound can be utilized in conventional "guest-host" and "twist nematic" displays as well as in unique helichromic displays. When used in helichromic displays, the helichromic compounds eliminate after-image scattering and enable the display to be operated at reduced voltages.

  A composition for use in thermally-addressable liquid crystal display devices, comprising a smectic liquid crystal material and a helichromic compound possessing both a chromophoric moiety and an optically-active moiety. The helichromic compound is a circularly dichroic dye capable of propagating incident visible light in a circularly polarized manner so that all polarizations of the incident light are absorbed. The composition comprising the helichromic compound can be utilized in thermally-addressable liquid crystal display devices to provide a display which operates at lower voltages, with faster response times, and higher contrast ratios.
