  摘要：

  The beneficial effects of thyroid hormone (TH) on lipid levels are primarily due to its action at the thyroid hormone receptor beta (THR-beta) in the liver, while adverse effects, including cardiac effects, are mediated by thyroid hormone receptor alpha (THR-alpha). A pyridazinone series has been identified that is significantly more THR-beta selective than earlier analogues. Optimization of this series by the addition of a cyanoazauracil substituent improved both the potency and selectivity and led to MGL-3196 (53), which is 28-fold selective for THR-beta over THR-alpha in a functional assay. Compound 53 showed outstanding safety in a rat heart model and was efficacious in a preclinical model at doses that showed no impact on the central thyroid axis. In reported studies in healthy volunteers, 53 exhibited an excellent safety profile and decreased LDL cholesterol (LDL-C) and triglycerides (TG) at once daily oral doses of 50 mg or higher given for 2 weeks.

  Polymer-of-prodrug (POP) materials enable new nucleoside reverse transcriptase inhibitor (NRTI) therapy strategies. The materials are prodrugs of NRTIs in the form of polymers. Suitable materials include products which are polymeric NRTI delivery systems comprising polymeric materials which are capable of degradation after administration to release NRTIs or NRTI prodrugs which themselves are capable of metabolism to the parent NRTIs. The NRTIs may optionally be selected from tenofovir (TFV), emtricitabine (FTC), lamivudine (3TC) and MK-8591 (EFdA). The invention facilitates long-acting (LA) regimens. Constructs of the materials may be in the form of injectable compositions or implants.

  A broadly based investigation of the effects of a diverse array of substituents on the photochemical rearrangement of p-hydroxyphenacyl esters has demonstrated that common substituents such as F, MeO, CN, CO₂R, CONH₂, and CH₃have little effect on the rate and quantum efficiencies for the photo-Favorskii rearrangement and the release of the acid leaving group or on the lifetimes of the reactive triplet state. A decrease in the quantum yields across all substituents was observed for the release and rearrangement when the photolyses were carried out in buffered aqueous media at pHs that exceeded the ground-state pK_aof the chromophore where the conjugate base is the predominant form. Otherwise, substituents have only a very modest effect on the photoreaction of these robust chromophores.

  一项关于各种取代基对对羟基苯乙酯光化学重排影响的广泛研究表明，常见取代基（如 F、MeO、CN、CO2R、CONH2 和 CH3）对光-Favorskii 重排和酸离去基团释放的速率和量子效率影响很小，对反应三重态的寿命影响也很小。当光解在缓冲水介质中进行时，pH 值超过发色团的基态 pKao（其中共轭碱是主要形式），则释放和重排的量子产率在所有取代基中都会降低。否则，取代基对这些坚固发色团的光反应影响很小。
