A series of furoxan-based nitric oxide-releasing chrysin and luteolin derivatives were synthesized.Pharmacological assays indicated that all chrysin and luteolin derivatives exhibited in vitro inhibit
Alkenal double bond reductases (DBRs) catalyze the NADPH-dependent reduction of the α,β-unsaturated double bond of many secondary metabolites.Two alkenal double bond reductase genes PaDBR1 and PaDBR2
A method for the direct arylation of 5-iodouracil and 5-iodouridine was found to proceed in moderate yields.By irradiating the 5-iodouracil or 5-iodouridine with a series of five-membered heterocycles
With the tool of Fourier series expansion,it is proved that there is no nonzero exact periodic solution in a class of the Riemann-Liouville fractional-order initial-valued systems (including the auton
Quasi-periodic motion is an oscillation of dynamic systems characterized by m basic frequencies ω1,ω2,…,ωm with m≥2,which are incommensurable with one another.
