摘要:
Disclosed herein is a method for inhibiting the premature polymerization of ethylenically unsaturated monomers comprising adding to said monomers an effective amount of: A) at least one nitroxyl compound, and B) at least one quinone alkide compound having an electron-withdrawing group at the 7-position. Additionally, a composition is disclosed that comprises: A) at least one nitroxyl compound, and B) at least one quinone alkide compound having an electron-withdrawing group at the 7-position.
摘要:
The present invention provides a method for making hypericin comprising the steps of converting a protohypericin to a protohypericin salt, and irradiating the protohypericin salt with visible light to form hypericin. The present invention also provides an apparatus comprising a transparent column having a top end and a bottom end, an inlet attached to the column at the top end to flow reactants into the column, a container attached to the column at the bottom end; and a visible light source positioned to cast light on to the column. The present invention further provides a method for making hypericin using said apparatus.
摘要:
This invention belongs to the chemical-pharmaceutical field. New compounds of pterocarpanquinone family presented in formula (I) according to this invention are capable to be activated by reduction generating alkylating species intracellularly. It presents selective cytotoxic effects particularly on mammalian human and nonhuman cells that divide constantly and are useful in treating diseases and dysfunctions related to the phenomenon of undesired cell proliferation. Such compounds are also effective for the treatment of diseases or dysfunctions related to high levels of TNF-α in human and nonhuman mammals.

The therapeutical use of tricyclic derivatives and pharmaceutically acceptable salts thereof having general formula (I), for treating diseases related to venous function deficiency and/or inflammatory oedema, is disclosed. In general formula (I), A is a sulphur or oxygen atom or a radical R3N where R3 is a hydrogen atom, a C1-5 alkyl radical or an optionally substituted aromatic or heteroaromatic ring; R1 is either a C1-5 alkyl radical, or a radical R4NH where R4 is a hydrogen atom, a C1-5 alkyl radical or an optionally substituted aromatic or heteroaromatic ring, or an aromatic ring optionally substituted by one or more acceptor or donor groupings, or a heteroaromatic ring having one or more heteroatoms and being optionally substituted by acceptor or donor groupings; and R2 is a hydrogen atom, a halogen atom, a C1-5 alkyl radical, an oxygen atom optionally substituted by a C1-5 alkyl radical, or a radical NR5R5', where each of R5 and R5' is independently a hydrogen or oxygen atom or C1-5 monovalent organic radicals.
