, p. 7576 - 7581 (2016/08/06)
The flexibility (or breathing behavior) of zinc-based metal-organic frameworks (MOFs) has been manipulated by regioisomeric and positional control of organic functionalities. Ten new regioisomeric BDC (ortho- or para-disubstituted benzene-1,4-dicarboxylic

This invention relates to compounds, pharmaceutical compositions and methods for use in the prevention and treatment of cerebral insufficiency, including enhancement of receptor functioning in synapses in brain networks responsible for basic and higher order behaviors. These brain networks, which are involved in regulation of breathing, and cognitive abilities related to memory impairment, such as is observed in a variety of dementias, in imbalances in neuronal activity between different brain regions, as is suggested in disorders such as Parkinson''s disease, schizophrenia, respiratory depression, sleep apneas, attention deficit hyperactivity disorder and affective or mood disorders, and in disorders wherein a deficiency in neurotrophic factors is implicated, as well as in disorders of respiration such as overdose of an alcohol, an opiate, an opioid, a barbiturate, an anesthetic, or a nerve toxin, or where the respiratory depression results form a medical condition such as central sleep apnea, stroke- induced central sleep apnea, obstructive sleep apnea, congenital hypoventilation syndrome, obesity hypoventilation syndrome, sudden infant death syndrome, Rett syndrome, spinal cord injury, traumatic brain injury, Cheney-Stokes respiration, Ondines curse, Prader-Willi''s syndrome and drowning. In a particular aspect, the invention relates to compounds useful for treatment of such conditions, and methods of using these compounds for such treatment.
Synthesis and Electrochemistry of Pyrimidoquinazoline-5,10-diones. Design of Hydrolytically Stable High Potential Quinones and New Reductive Alkylation Systems

The synthesis of pyrimidoquinazoline-5,10-diones 1 and pyrimidoquinazoline-5,10-diones 2 was carried out in conjunction with the design of both hydrolytically stable high potential quinones and new purine-like reductive alkylators.These systems consist of a benzoquinone ring bearing two fused pyrimidin-4(3H)-one rings.The fused pyrimidinone rings serve to protect 1 and 2 from hydrolysis as well as to raise quinone redox potentials by stabilizing the hydroquinones with internal hydrogen bonds (65 mV increase per hydrogen bond).Synthesis of 1 and 2 involved pyrimidinone ring annelation to a 2,5-diamino-3-nitroterephthalic acid derivative and to a 2,4-diamino-1,5-dicarboxy-3-nitrobenzene derivative, respectively.The synthetic studies provided insights into the electronic effects of nitro and amino groups on the annelation process.
Bisazo brown reactive dye
-
, (2008/06/13)
A brown reactive dye represented by a free acid of the formula, STR1 wherein R is a hydrogen atom or a C1 to C4 alkyl group, X is --SO2 CH2 CH2 Cl, --SO2 CH=CH2, --SO2 CH2 CH2 OSO3 H or --SO2 CH2 CH2 OPO3 H2, rings A, B and C are each a benzene or naphthalene ring which may have other substituent, m is 0 to 3 and n is 0 to 1. This dye is suitable for dyeing cellulose fibers brown to afford dyeings superior in fastnesses, acid stability, build-up property and level dyeing property.

, (2008/06/13)
Azo dyestuffs, which in the acid form, are represented by the formula: wherein A is an aromatic radical, M is a 1,4-benzene radical which may be substituted, E is the residue of a coupling component which is free from azo groups, At least one of A and M containing a phosphonic acid group, and the metal complexes of those having a metallisable group are reactive dyes suitable for use in the process of German OLS No. 2324809.
