An indazole hydrazide compound, as represented in formula (I); wherein, R is selected from substituted alkyl, substituted alkenyl and substituted phenyl; substituent in the substituted alkyl and substituted alkenyl includes phenyl and/or substituted phenyl; R′ is selected from H and alkyl. Compared with the prior art, the above indole hydrazide compound can be used as integrin avβ3 receptor antagonist. Besides, it has obvious anti-prostate cancer activity and has a significant inhibitory effect on enzalutamide-resistant cell lines. In addition, the above-mentioned compound has obvious anti-tumor angiogenesis activity and can be used in the preparation of anti-tumor angiogenesis drugs to inhibit tumor angiogenesis.

Indazole hydrazide compound and application thereof

Disclosed in embodiments of the present invention are a synchronous control method and system for a laser test of an optical engine. The operation of a laser can be driven by the synchronous control system. When a test of a data point is finished and the optical engine stops for optical window cleaning, the laser may still maintain stable operation under the driving of the synchronous control system, experiments may be directly carried out next time, and thus, laser test efficiency of the optical engine can be improved. Moreover, the synchronous control system is adopted to independently drive the laser to achieve energy stability before experiments, preventing an influence of long-term operation on the performance of the optical engine, and improving test accuracy.

Synchronous control method and system for laser test of optical engine

The present disclosure relates to a method and system for monitoring on route transportations. The method includes obtaining a driving route of a target vehicle; obtaining a reference position on the driving route away from a first current position of the target vehicle; determining a second current position of the target vehicle after a reference time; determining a distance between the second current position and the reference position is greater than a preset distance; and sending a signal to a target terminal indicating that the target vehicle is off-route.
