Magnetic Field Dependent Reaction Yields from Radical Ion Pairs Linked by a Partially Rigid Aliphatic Chain
Werner, Udo,Kuehnle, Wolfgang,Staerk, Hubert
, p. 9280 - 9287 (1993)
The electron donor-acceptor compound pyrene-(CH2)3-cyclohexane-(CH2)3-dimethylaniline, abbreviated as Py3(C6)3DMA, has been investigated.Photoinduced electron transfer leads to the singlet radical ion pair Py-3(C6)3DMA+.An extraordinary large and distinct magnetic field effect is observed in the yield of the locally excited triplet state of the pyrene moiety, the recombination product of the triplet radical ion pair.The half-width of the "J-resonance" maximum in the magnetic field dependent triplet yield curve is just 66 G, corresponding to 7.7*10-7 eV or 6.2*10-3 cm-1.This is due to the influence of the rigid trans-cyclohexane part in the aliphatic chain, which leads to a reduced intramolecular mobility and to a narrow probability distribution of the radical ion pair distance, as predicted by Monte-Carlo computer simulations.The magnetic field dependence of the triplet generation is further transmitted to secondary reactions like triplet-triplet annihilation, thus leading to a magnetic field dependent delayed fluorescence and to a delayed excimer fluorescence.

In this study, a series of novel hydroxyamidine derivatives were identified as potent and selective IDO1 inhibitors by structure-based drug design. Among them, compounds 13-15 and 18 exhibited favorable enzymatic and cellular activities. Compound 18 showed improved bioavailability in mouse, rat, and dog (F% = 44%, 58.8%, 102.1%, respectively). With reasonable in vivo pharmacokinetic properties, compound 18 was further evaluated in a transgenic MC38 xenograft mouse model. The combination of compound 18 with PD-1 monoclonal antibody showed a synergistic antitumor effect. These data indicated that compound 18 as a potential cancer immunotherapy agent should warrant further investigation.

Preparation method of trans-1,4-cyclohexane dicarboxylic acid monomethyl ester
-
Paragraph 0027-0041, (2018/07/06)
The invention discloses a preparation method of trans-1,4-cyclohexanedicarboxylic acid monomethyl ester. The preparation method comprises the following steps of using cis and trans mixed type dimethyl1,4-cyclohexanedicarboxylate with better solvent property in organic solvents as the raw material, performing isomerization reaction under the catalyzing action of an organic alkaline catalyst, and performing high-selectivity monoester hydrolyzing under the action of inorganic alkaline, so as to obtain the trans-1,4-cyclohexanedicarboxylic acid monomethyl ester. Compared with the prior art, the preparation method has the advantages that (1) the used raw material has good dissolvability in the organic solvent, such as methyl alcohol; (2) by adopting the optimized catalyst, the activating energy of the isomerization reaction is reduced, the isomerization time is shortened, the reaction energy consumption is decreased, the cost is reduced, and the optimized catalyst is suitable for industrialized production; (3) the hydrolyzing of diester is effectively reduced, the amount of diacid byproducts is reduced to be 2% or lower, and the product purity is improved; (4) a small amount of unreacted raw material is sent into an organic phase via an extracting procedure, and is separated from the product at high efficiency, so that the purity of the product is further improved.
