Abstract:
L'invention vise un procédé de synthèse d'un composé hydrocarboné linéaire α- ω-bifonctionnel symétrique répondant à la formule suivante R 1 -(CH2) 5 -R 2 -(CH2) 5 -R 1 dans laquelle R 1 est -COOR 3 , R 3 étant soit H soit un radical alkyle comportant de 1 à 4 atomes de carbone ou -CH2NH2 et R2 représente un radical alkylène choisi entre -CH=CH- et -CH 2 -CH 2 - caractérisé en ce que dans une première étape on effectue l'homométathèse catalytique du 7-octénal pour former l'α-ωdialdéhyde de formule OHC-(CH 2 ) 5 -CH=CH-(CH 2 ) 5 -CHO puis, dans une deuxième étape, on soumet ce dialdéhyde soit à une réaction d'oxydation, soit une réaction d'amino réduction et enfin, dans une troisième étape, optionnelle, on hydrogène la liaison éthylénique pour former le composé saturé.
Abstract:
Compounds of the Formula (I): E-NH-D-NH-B-A-B-NH-D-NH-E, wherein A is C2-C6 alkene, C3-C6 cycloalkyl, cycloalkenyl, or cycloaryl; B is independently a single bond, C1-C6 alkyl alkenyl; D is independently C1-C6 alkyl or alkenyl, or C3-C6 cycloalkyl, cycloalkenyl, or cycloaryl; and E is independently H, C1-C6 alkyl or alkenyl; and pharmaceutically suitable salts thereof; a synthetic method therefor, pharmaceutical dosage forms containing one of more of these compounds, and use of these compounds in the treatment of neoplastic cell growth, are disclosed.
Abstract:
The flame-retardants of this invention were formed by the direct reaction of ethyleneamines and commercial polyphosphoric acid at an elevated temperature. It was unexpected that a high temperature had to be used to overcome reaction barrier to formation. These compounds are found to be efficient flame retardants.

Abstract:
The present invention relates to the use of polyaminoisoprenylderivatives in antibiotic or antiseptic treatment of bacteria including those presentingmultiple drug resistance (MDR), in particular as efflux pump inhibitors. It also relates to novel polyaminoisoprenylderivatives, compositions comprising the same, process for preparing the same, and use thereof in antibiotic or antiseptic treatment.
Abstract:
Novel conformationally restricted polyamine analogs are provided, as well as compositions comprising these novel polyamine analogs. Methods of using the novel polyamine analogs in treatment of diseases such as cancer are also provided. Also provided is a method of delivering these analogs specifically to tumor cells by covalently attaching polyamine analogs to porphyrin compounds, along with novel polyamine-porphyrin covalent conjugates.
Abstract:
The present invention provides processes for producing amine-containing compounds such as diammonium salts and amino acid derivatives comprising the steps of subjecting a salt of an amine bearing an unsaturated group to a self-metathesis reaction with itself to produce a diammonium salt or to a cross-metathesis with a suitable α,β-unsaturated acid, ester or amide to form an amino acid salt or a derivative thereof. The salts produced by the metathesis reactions can then be subjected to hydrogenation to reduce the double bond which is formed in the metathesis reaction.
Abstract:
The invention provides novel polyamine compounds and pharmaceutical compositions for administration in conjunction with cancer chemotherapy or radiation therapy. The compounds are administered locally to provide protection against the adverse side-effects of chemotherapy or radiation therapy, such as alopecia, mucositis and dermatitis. Pharmaceutical preparations comprising one or more chemoprotective polyamines formulated for topical or local delivery to epithelial or mucosal cells are disclosed. Methods of administering the pharmaceutical preparations are also disclosed.
Abstract:
Compounds having the formula (I): (R1R2N)CH2-CH=CH-CH2(NR3R4) wherein R1, R2, R3 and R4, which may be the same or different represent hydrogen atoms, an alkyl group having from 1 to 6 carbon atoms, a cycloalkyl group of 3 to 6 carbon atoms, a heterocyclic group, an aryl group, a heteroaryl group having from 3 to 6 atoms, an amidino group or R1, R2 and/or R3 and R4 together represent a carbocyclic or heterocyclic group comprising from 3 to 6 atoms with the proviso that R1, R2, R3 and R4 cannot simultaneously represent hydrogen and salts thereof are fungicides especially mildewicides. Preferred compounds are those wherein the groups R represent methyl or ethyl groups.
