Synthesis of novel phthalazine-based derivatives with potent cytotoxicity against HCT-116 cells through apoptosis and VEGFR2 inhibition.

The parent ethyl 3-(4-benzyl-1-oxophthalazin-2(1)-yl) propanoate (3) has 25 compounds.

The ester 3 was hydrazinolyzed to give the corresponding hydrazide 3-(4-benzyl-1-oxophthalazin-2(1)-yl) propanehydrazide (5), then azide 6 coupled with amino acid ester hydrochloride and/or amines to afford several parent esters 8a-c, then a series of hydrazinolyzed reactions occurred to give corresponding hydrazides 9a-c.

A modified particle swarm optimization rat search algorithm and its engineering application.

Solar energy generation requires photovoltaic (PV) systems to be optimised, regulated, and simulated with efficiency. The performance of PV systems is greatly impacted by the fluctuation and occasionally restricted accessibility of model parameters, which makes it difficult to identify these characteristics over time. To extract the features of solar modules and build highly accurate models for PV system modelling, control, and optimisation, current-voltage data collecting is essential.
