(R/S)-4,4′-Dimethoxy-5,6,5′,6′-dimethenedioxy-2, 2′-di-(4(S)-methyl-oxazoline-1)-biphenyl has been synthesized from dimethyl-4,4′-dimethoxy-5,6,5′,6′-dimethenedioxy-biphenyl-2, 2′-dicarboxylate, and then the diastereoisomer mixture was almost fully converted to a single diastereoisomer with S-configuration ((S)-3) through the key configuration transform promoted by CuI, which was confirmed by CD, HPLC and 13C NMR. The C2-symmetric biphenyl, (S)-dimethyl-4,4′-dimethoxy-5,6,5′,6′-dimethenedioxy-biphenyl- 2,2′-dicarboxylate was prepared easily via the hydrolysis and ester exchange of (S)-3.

A novel series of tacrine-bifendate (THA-DDB) conjugates (7a-e) were synthesized and evaluated as potential anti-Alzheimer's agents. These compounds showed potent cholinesterase and self-induced β-amyloid (Aβ) aggregation inhibitory activities. A Lineweaver–Burk plot and molecular modeling study showed that these compounds can target both catalytic active site (CAS) and peripheral anionic site (PAS) of acetylcholinesterase (AChE). The cytotoxicity of the conjugate 7d against PC12 and HepG2 cells and hepatotoxicity against human hepatocyte cell line (HL-7702) were found to be considerably less compared to THA. Moreover, treatment with 7d did not exhibit significant hepatotoxicity in mice. Finally, in vivo studies confirmed that 7d significantly ameliorates the cognitive performances of scopolamine-treated ICR mice. Therefore, 7d has high potential for the treatment of Alzheimer's disease and warrants further investigation.

Method for preparing bicyclol by using bifendate
-
Paragraph 0081; 0086; 0091; 0097, (2017/10/26)
The invention discloses a method for preparing bicyclol by using bifendate, and belongs to the technical field of the chemical synthesis. The method comprises the following steps: using the bifendate as an initial raw material, hydrolyzing by using strong base, acidizing to obtain biphenyl dioic acid, dehydrating the biphenyl dioic acid to obtain biphenyl anhydride, reducing the biphenyl anhydride to obtain biphenyl alcohol acid, and finally esterifying to obtain the bicyclol. A product synthesized by the method is white solid, and the melting point of the white solid is 138-140 DEG C. The white solid can be determined as the pure bicyclol through a liquid chromatography-mass spectrometry and a nuclear magnetic resonance spectrometry. The method has the characteristics of cheap cost, short synthetic route, high yield, moderate reaction condition, simple post-treatment, and larger industrialized potential.

scheme or table, p. 801 - 805 (2012/03/11)
Novel furoxan-based nitric oxide (NO)-releasing DDB derivatives (7a-j) were synthesized. Compounds 7i and 7j significantly reversed the resistance of MCF-7/Adr cells to doxorubicin in the combination treatment, and markedly increased the intracellular accumulation of doxorubicin probably via inhibiting Pgp-mediated intracellular drug efflux as well as down-regulating doxorubicin-induced Pgp expression. It was demonstrated that NO released by 7i and 7j played an important role in increasing intracellular doxorubicin accumulation and chemo-sensitizing MCF-7/Adr cells to doxorubicin, and the synergic effects of DDB and NO-donor moieties in 7i and 7j may contribute to reversing Pgp-mediated MDR in MCF-7/Adr cells to doxorubicin.

Liquid chromatography resolution of biphenyl dimethyl dicarboxylate (DDB) and its analogues on a chiral stationary phase

Racemic biphenyl dimethyl dicarboxylate (DDB) and its analogues have been successfully resolved on a commercial HPLC chiral column, (3R,4S)-Whelk-O 1. In general, cyclic amide analogues of DDB, which were derived from pyrrolidine or piperidine, showed greater enantioselectivity and greater retention than the corresponding N,N-dialkyl amide or N-alkyl amide or ester analogues. From these results, it was concluded that the carbonyl oxygen of the DDB analogues plays an important role as a hydrogen bond acceptor, though the steric bulkiness of the amide functionality of DDB analogues may be another factor governing chiral recognition. The conformational stability of the two enantiomers of DDB and its analogues was also found to be high enough for the two enantiomers to be resolvable on (3R,4S)-Whelk-O 1.
