Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C8H7NO2. Introducing a new discovery about 57319-65-0, Name is 6-Aminoisobenzofuran-1(3H)-one
Pyrophthalones VII.Synthesis and anti-inflammatory activity of 2-(4-pyridinyl)indane-1,3-diones diversely substituted on the benzene ring.Access routes to 2-(1,4-dihydro 4-pyridinylidene) indane-1,3-diones diversely substituted on the benzene ring are studied.The regiospecific attack of these beta diketoenamines by alkyl iodides leads to N-substituted compounds.These derivatives may be obtained by any of three possible methods: (1) condensation of 4-methyl pyridine with ethyl phthalates in the absence of catalyst; (2) oxidative condensation of N-alkyl-pyridinium bromides with indane-1,3-diones; (3) aminolysis of 2-(4-4H-pyranylidene) indane-1,3-diones.Pharmacomodulation by the introduction of oxygen or sulfur containing functions (ether, thioether, alcohol, ketone, acid, ester, amide) on the nitrogen of the basic molecule is not very fruitful; only the acetic derivative 19 manifests marked antiinflammatory activity unaccompanied by anti-coagulant action.The presence of chloro, nitro or methoxyl groups on 5 after N-substitution by ethyl or piperidinylethyl groups appears to be more favorable.The most active compound 57 decreases prostaglandin production and leukocyte migration without affecting either cyclooxygenase or 5-lipoxygenase.Its interference, direct or indirect, with phospholipasic A2 activity may be envisaged in particular.Keywords – 2-(4-pyridinyl)indane-1,3-diones / heterocyclic beta diketoenamines / partition coefficient / anti-inflammatory activity / mechanism of action
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C8H7NO2, you can also check out more blogs about57319-65-0
