the condensation of glyoxal with benzylamine in the presence of formaldehyde leads to 2,4,6,8-tetrabenzyl-2,4,6,8-tetraazabicyclo [3.3.0] octan (6) in methanol. the scopes and limitations of the reaction have been determined. at low temperatures, a mixture of (6) and diol (7) is formed.

condensation of glyoxal, formaldehyde and anilines lead to the formation of 2,4,6,8- tetraphenyl and substituted phenyl 2,4,6,8-tetraazabicyclo [3.3.0] octanes. the reactions are sensitive to ph and temperature. ortho derivatives of anilines do not participate in this condensation. x-ray structural determination reveals a cis-dienvelope geometery about the two fused rings.

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...
Increased -synuclein ( syn) and mitochondrial dysfunction play central roles in the pathogenesis of Parkinson’s disease (PD), and lowering syn is under intensive investigation as a therapeutic strategy for PD. Increased syn levels disrupt mitochondria and impair respiration, while reduced syn protects against mitochondrial toxins, suggesting that interactions between syn and mitochondria influe...
Post-mortem analyses of brains from patients with Parkinson disease who received fetal mesencephalic transplants show that α-synuclein-containing (α-syn-containing) Lewy bodies gradually appear in grafted neurons. Here, we explored whether intercellular transfer of α-syn from host to graft, followed by seeding of α-syn aggregation in recipient neurons, can contribute to this phenomenon. We asse...
