摘要:
The invention relates to a rubber blend containing silicic acid, said blend being produced from at least one rubber, an alkoxysilane containing sulphur, a vulcanising agent, a filler and optionally other auxiliary products for rubber. The blend contains between 0.1 and 1 parts by weight, in relation to 100 parts by weight of rubber used, of a polysulphide additive of formula (I), where x represents 0, 1, 2, 3 or 4, and A and B, independently of one another represent an optionally derivatised carboxyalkyl-, carboxyaryl- or hydroxyaryl group. Said blend has between 0.1 and 15 parts by weight, in relation to 100 parts by weight of rubber used, of 1.6-bis(N,N-dibenzylthiocarbamoyldithio)hexane (CAS No.: 151900-44-6).

摘要:
Small molecule inhibitors of Stat3 and their derivatives are disclosed. Also described are methods to inhibit cell growth by use of Stat3 inhibitors, and the use of Stat3 inhibitors for the prevention and/or treatment of cancer. Further, inhibitors of Stat3 that also do not inhibit Statl are described as well as their derivatives. Methods of screening additional compounds for Stat3 inhibition activity and/or non-inhibition of Statl activity are also described herein.
摘要:
Disclosed are thioethers, methods for preparing such thioethers, and curable compositions, such as coating and sealant compositions, that include such thioethers. The thioethers can be the reaction product of (a) an alpha, omega dihalo organic compound, (b) a metal hydrosulfide, and (c) a metal hydroxide.
摘要:
Methods and compositions comprising N-acetylcysteine amide (NAC amide) and derivatives thereof are used in treatments and therapies for human and non-human mammalian diseases, disorders, conditions and pathologies. Pharmaceutically or physiologically acceptable compositions of NAC amide or derivatives thereof are administered alone, or in combination with other suitable agents, to reduce, prevent, or counteract oxidative stress and free radical oxidant formation and overproduction in cells and tissues, as well as to provide a new source of glutathione.
摘要:
Novel arylsulfonamide ether compounds and pharmaceutical compositions thereof are described. The use of the novel arylsulfonamide ether compounds and pharmaceutical compositions thereof as inhibitors of interleukin-1β converting enzyme and other cysteine proteases in the ICE family is also described. In addition, methods of treating stroke, inflammatory diseases, septic shock, repurfusion injury, Alzheimer's disease, and shigellosis using a compound of the invention or a pharmaceutical composition thereof are described.
摘要:
A process is provided for the manufacture of liquid polysulfide polymers. In particular, the process allows for making the liquid form of the polysulfide polymer directly and eliminates the need to first make a solid polysulfide polymer and then convert it to a liquid.
