Chemistry is traditionally divided into organic and inorganic chemistry. Reference of 165253-29-2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 165253-29-2
The present invention relates to thienopyridazine compounds of formula (I), their pharmaceutically acceptable salts or hydrates, wherein R1 and R2 are independently H or C1-4 alkyl, R3 is a saturated or unsaturated 5- or 6- membered ring containing N, S or O, or its optical isomers, R4 is a halophenyl monosubstituted or disubstituted at any position. The present invention provides the preparation methods of these compounds, pharmaceutical compositions containing these compounds and the uses of these compounds, particularly in treating cancer.
Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 165253-29-2. Reference of 165253-29-2
