摘要:
A synergic pharmaceutical composition, useful for inhibiting human or animal neovascularization (angiongenesis) of the cornea, retina and other organs, characterized in that it comprises, in a pharmaceutically acceptable vehicle or carrier: 60 to 90% in weight of Suramine, or the equivalent of one of the pharmaceutically acceptable salts thereof; and 40 to 10% of Bevacizumab; wherein said percentages are with respect to the sum of the weights of both active principles. Said synergic pharmaceutical composition is presented in the form of an composition injectable by endovenous, intravitreous or subconjunctival route, or in the form for topical administration.
摘要:
8-(anilino)-1-naphthalenesulfonate (ANS) analogs and methods for their use in analyte detection assays are provided. The subject ANS analogs are characterized by having at least one non-hydrogen substituent on their phenyl moiety and producing a reaction product with 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) or an analog thereof, e.g. MBTHSB, that exhibits reduced drift. In certain preferred embodiments, the subject ANS analogs are described by formula (I) wherein: n is 1 to 5; and X is a substituent other than H. The subject ANS analogs find use in a variety of applications, particularly in analyte detection assays, such as glucose detection assays.

摘要:
Beim Ausfällen von 2-Naphthylamin-1.5-disulfonsäure-Mononatriumsalz aus den Sulfiergemischen, die die freie Sulfonsäure als Reaktionsprodukt enthalten, durch Verdünnen und Zugabe von Natriumionen abgebenden Verbindungen erhält man ein Produkt höherer Reinheit mit einem niedrigeren Gehalt anhaftender Schwefelsäure, wenn man die Fällung durch Verdünnen der Reaktionsgemische und Zugabe von Natriumionen abgebenden Verbindungen unter exakt definierten Bedingungen vornimmt.
