Synthesis and evaluation of polymers for use in early warning fire alarm devices [PDF]

open access: yes
Conjugated polyacetylene polymers and one condensation polyene, all containing a high degree of conjugated unsaturation, were synthesized. These polymers were characterized by chemical analysis and by thermogravimetric analysis, as well as for their film-

Synthesis, molecular modelling and anticancer evaluation of new pyrrolo[1,2-b]pyridazine and pyrrolo[2,1-a]phthalazine derivatives

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
Two new series of heterocyclic derivatives with potential anticancer activity, in which a pyrrolo[1,2-b]pyridazine or a pyrrolo[2,1-a]phthalazine moiety was introduced in place of the 3′-hydroxy-4′-methoxyphenyl ring of phenstatin have been synthesised ...

Chemistry - ACS Certification [PDF]

open access: yes, 2011
Heterocyclic organic and organometallic compounds (e.g. polypyrrole, Figure 1A) and their derivatives have been of great interest for conductive polymers due to their novel properties, such as their versatile structure and ease of synthesis. In addition,

Polynitrogen Bicyclic and Tricyclic Compounds as PDE4 Inhibitors

open access: yesApplied Sciences
We report here two new series of designed PDE4 inhibitors, the first one showing the quinoline scaffold recently investigated by us through a fragment-based drug design strategy, and the second consisting of pyrazolo [1′,5′:1,6]pyrimido[4,5-d]pyridazine ...

Understanding of the bond dissociation energy of C-NO2 in five- and six-membered N-heteroaromatic derivatives

open access: yesFirePhysChem
A clear structure-sensitivity relationship in energetic molecules is beneficial for designing energetic materials. At the molecular level, sensitivity is closely related to the bond dissociation energy (BDE) of trigger linkages like C/N/O-NO2 in the ...
