In the title compound {systematic name: 2-[(E)-but-2-en-1-yl]isoindoline-1,3-dione}, C(12)H(11)NO(2), the phthalimide ring system is essentially planar, with a maximum deviation of 0.008 (1) Å, while the plane of the N-crotyl substituent is orthogonal to the phthalimide ring system, making a dihedral angle of 87.5 (1)°.
Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, be...
Twelve related monocation chalconium salts [{Nap(EPh)(E'Ph)Me}(+){CF(3)SO(3)}(-)] 2-4, [{Acenap(Br)(EPh)Me}{CF(3)SO(3)}(-)] 5-7, and [{Acenap(EPh)(E'Ph)Me}(+){CF(3)SO(3)}(-)] 8-13 have been prepared and structurally characterized. For their synthesis naphthalene compounds [Nap(EPh)(E'Ph)] (Nap = naphthalene-1,8-diyl; E/E' = S, Se, Te) N2-N4 and associated acenaphthene derivatives [Acenap(X)(EPh...
Two enzymes are responsible for the cleavage of pregnane side chains. A steroid-inducible oxygenase, in the presence of reduced nicotinamide adenine trinucleotide and molecular oxygen, catalyzes the conversion of progesterone into testosterone acetate. The latter ester is then hydrolyzed by an esterase to yield testosterone. The oxygenase has been partially purified and separated from the ester...
