Relation between structure and metabolic pathway for tricyclic compounds: Relation between structure and metabolic pathway for tricyclic compounds. Frigerio, A.; De Pascale, A.; Pantarotto, C. (Ist. Ric. Farmacol. "Mario Negri", Milan, Italy). Boll. Chim. Farm., 115(12), 817-32 (Italian) 1976. CODEN: BCFAAI. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) After i.p. administration of 5H-dibenzo[a,d]cycloheptene (I) [256-81-5] and 5H-dibenzo[b,f]azepine (iminostilbene) (II) [256-96-2] to rats (80 mg/kg), the corresponding 10,11-epoxide and 10,11-dihydro-10,11-dihydroxy derivs. of each compd. were identified as urinary metabolites by gas chromatog.-mass spectrometry. The same metabolites were also produced by incubating I and II with rat liver microsomes. Proposed fragmentation schemes in the mass-spectrometric reactions of these compds. are presented. The formation of an epoxide metabolite and its corresponding dihydrodiol seems to be a route common to tricyclic compds. of this type having a double bond at position 10,11.

Synthesis and reactions of polymers with photoactive terminal groups: Synthesis and reactions of polymers with photoactive terminal groups. 1. Kinetics and mechanisms of radical and anionic coupling of N-acetyldibenz[b,f]azepine units to polymer molecules. Alimoglu, Ali Kamal; Bamford, C. H.; Ledwith, A.; Mullik, S. U. (Dep. Inorg., Phys. Ind. Chem., Univ. Liverpool, Liverpool, Engl.). Macromolecules, 10(5), 1081-5 (English) 1977. CODEN: MAMOBX. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Poly(Me methacrylate) (I) [9011-14-7] and polystyrene (II) [9003-53-6] with dibenzazepine end groups, introduced by free radical or anionic methods, were chain extended by photocyclodimerization. Photoinitiated free-radical polymn. of styrene employing Mn2(CO)10 and N-(bromoacetyl)dibenz[b,f]azepine (III) [31552-96-2], prepd. by reaction of dibenz[b,f]azepine [256-96-2] with bromoacetyl bromide [598-21-0], gave II with 2 dibenzazepine end groups/chain, also prepd. by reaction of double-ended living II with III. Because of a different termination mechanism photoinitiated polymn. of Me methacrylate with Mn2(CO)10-III gave I with an av. 1.21 dibenzazepine end groups/chain. Chain extension of dibenzazepine-terminated I and II was photosensitized by benzophenone or benzil. Similar photoinitiated chain extension of dibenzazepine-terminated divinylbenzene-styrene copolymer [9003-70-7] caused crosslinking, with complete gelation after irradn. times of 15-30 min.
