Paragraph 0170-0174, (2021/06/22)
The invention provides a compound as shown in a general formula (I). The compoundcan be used for an organic electroluminescent device as a guest material of a luminescent layer. The compound comprises a natural heterocyclic ring and iridium (Ir) coordinated structure, and the light emitting wavelength of the compound can be effectively regulated and controlled. When the compound is used as a guest material of a light-emitting layer, the light-emitting efficiency and the light stability of the organic electroluminescent device can be improved. In addition, the compound provided by the invention is small in molecular weight, is applied to a light-emitting layer, is relatively low in evaporation temperature, and is beneficial to processing. The invention also provides a luminescent layer guest material containing the compound shown in the general formula (I), an organic electroluminescent device and a display device.

In this study, we report the identification of potent pyrimidoindazoles as phosphodiesterase10A (PDE10A) inhibitors by using the method of fragment-based drug discovery (FBDD). The pyrazolopyridine derivative 2 was found to be a fragment hit compound which could occupy a part of the binding site of PDE10A enzyme by using the method of the X-ray co-crystal structure analysis. On the basis of the crystal structure of compound 2 and PDE10A protein, a number of compounds were synthesized and evaluated, by means of structure-activity relationship (SAR) studies, which culminated in the discovery of a novel pyrimidoindazole derivative 13 having good physicochemical properties.

(Chemical Equation Presented) A total synthesis of streptonigrone, 1, is described, which incorporates a one-step synthesis of substituted pyridones devised in our laboratory. Other aspects of the synthesis that differentiate the present approach from previous ones are the use of a Conrad-Limpach reaction, rather than the customary Friedlaender methodology, to assemble the quinoline segment of 1, and the implementation of an anionic sequence for the functionalization of a key pyridone intermediate.
