Patent number: 5420136Abstract: A class of predominantly hydrophobic non-azo N-substituted 1,8-naphthalimide compounds, each bearing, at its 3-position, a nucleofuge and, at its 4-position, a heteroatomic electron-releasing group. The heteroatomic electron-releasing group is being characterized as having a heteroatom directly linked to the 4-position of the ring, and having at least one hydrogen directly attached to the heteroatom. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species initiate chemical changes in lipid bilayer membranes of viruses and other target cells. These changes can eradicate viruses and other target cells. The activated species can also cause structural changes in lipid and any associated proteins and polypeptides at a level beneath the surface of the membrane, leading to polymerization and crosslinking.Type: GrantFiled: August 9, 1993Date of Patent: May 30, 1995Assignee: MicroBioMed CorporationInventors: David E.

Patent number: 4371694Abstract: Compounds of Formula I or Formula II ##STR1## where A is an electron withdrawing group and B is a secondary or tertiary amino group or the group OD where D is H, aryl or an aliphatic group are made by reacting a corresponding compound of Formula Ia or Formula IIa ##STR2## in a solvent with a reagent selected from organic primary and secondary amines and compounds of the formula MOD where M is an alkali metal and A and D are as defined above. In this process the nitro group and the group B in Formula I and Ia are in the 2- or 4- position and the compounds of Formula I, Ia, II and IIa may optionally be further substituted. Preferably a primary or secondary amine is reacted with a compound of formula Ia, preferably using dimethylformamide as solvent. The process can result in the production of novel compounds, including (1) Compounds of Formula III wherein each group A is CO.sub.Type: GrantFiled: July 1, 1980Date of Patent: February 1, 1983Assignee: Brent Chemicals International LimitedInventors: Michael S. Alexiou, Philip I. Brittain, John H. P. Tyman

Patent number: 4200752Abstract: The present disclosure is directed to novel quenchable, fluorescent dyestuffs which are substantially soluble in low surface tension, substantially non-polar oily solvents, e.g., refined kerosene, and are trisubstituted 4-aminonaphthalimides having the structure formula: ##STR1## wherein R.sub.1 is a member selected from the group consisting of:(a) alkyl groups having from two to twelve carbon atoms,(b) substituted akyl groups having at least two carbon atoms,(c) phenylalkyl groups whose alkyl moiety has from one to four carbon atoms and(d) alicyclic rings having from five to six carbon atoms in the alicyclic ring;R.sub.2 and R.sub.Type: GrantFiled: February 16, 1978Date of Patent: April 29, 1980Inventor: Robert C. Bertelson

Patent number: 4172202Abstract: N-substituted amides or optionally N-substituted hydrazides of 4-amino-naphthalic acids which may be substituted in 3-position by a sulfo group are obtained by reacting 4-halo-1,8-naphthalic anhydride with a primary amine or an optionally N-substituted hydrazine having a pK.sub.a -value of at least 8, exchanging in the so-obtained 4-halo-naphthalimide the halogen for the amino group by reacting it with ammonia and, optionally, subsequent sulfonation. The products are dyeing matters useful for the coloration of synthetic fibers, plastics, oils, waxes, resins, paper, printing pastes, lacquers or natural polyamides, especially for daylight-fluorescence pigments.Type: GrantFiled: January 9, 1978Date of Patent: October 23, 1979Assignee: Hoechst AktiengesellschaftInventor: Theodor Papenfuhs

Patent number: 4169203Abstract: Acetylation of residual primary and secondary alkyl amine groups present in the structure of polymeric colorants and the acetylated colorant products are disclosed. The acetylation is a post production step. The acetylation improves the colorants' water solubility.Type: GrantFiled: November 18, 1976Date of Patent: September 25, 1979Assignee: DynapolInventors: Robert E. Wingard, Daniel J. Dawson
