The present invention relates to amide substituted indazoles and benzotriazoles which are inhibitors of the enzyme poly (ADP-ribose) polymerase (PARP), previously known as poly (ADP-ribose) synthase and poly (ADP-ribosyl) transferase. The compounds of the present invention are useful as mono-therapies in tumors with specific defects in DNA-repair pathways, as enhancers of certain DNA-damaging agents such as anticancer agents and radiotherapy, for reducing cell necrosis (in stroke and myocardial infarction), regulating inflammation and tissue injury, treating retroviral infections, and protecting against the toxicity of chemotherapy.

The present invention relates to a process for the preparation of an (hetero)arylamine, wherein an optionally substituted (hetero)aromatic bromide compound is contacted with a nucleophilic organic nitrogen-containing compound in the presence of a base, and a catalyst comprising a copper atom or ion and at least one ligand, said ligand comprising at least one coordinating oxygen atom, and if said oxygen atom is part of an OH group, then said OH group is attached to an aliphatic spa carbon atom or to a vinylic carbon atom.
A lithium ion battery separator includes a porous film of a polymeric chelating agent. The polymeric chelating agent includes a poly(undecylenyl-macrocycle), where the macrocycle is a chelating agent. A positive electrode includes a structure and a coating formed on a surface of the structure. The structure includes a lithium transition metal based active material, a binder, and a conductive carbon; and the coating includes a poly(undecylenyl-macrocycle), where the macrocycle is a chelating agent. The separator and/or positive electrode are suitable for use in a lithium ion battery.

The polyvinyl alcohol of the present invention is a partially saponified polyvinyl alcohol having a saponification degree of 70 to 98 mol% and containing a larger amount of methanol-soluble substances than that contained in polyvinyl alcohols having the same saponification degree obtained by known processes, and is novel.
The process for producing polyvinyl alcohol of the present invention comprises saponifying polyvinyl esters in a solvent of a polyoxyalkylene ether having in the molecule thereof a structural unit represented by the general formula [I]:
wherein R' and R2 each represents an alkylene group having 2 to 5 carbon atoms in the main chain thereof, which may be substituted with a lower alkyl group or lower alkoxy group; t is an integer of 0 or 1; m and n each represents 0 or an integer of 1 to 10; and I + m + n > 2;
with the catalyst of an organic (aliphatic or aromatic) sulfonic acid at an elevated temperature in the presence of water. The process can produce polyvinyl alcohol having a higher saponification degree at a higher reaction rate than conventional hydrolysis processes catalysed by acids.
本发明的聚乙烯醇是一种部分皂化的聚乙烯醇,其皂化度为 70 至 98 摩尔%,与通过已知工艺获得的具有相同皂化度的聚乙烯醇相比,含有更多的甲醇可溶物,具有新颖性。
本发明生产聚乙烯醇的工艺包括在聚氧亚烷基醚的溶剂中对聚乙烯醇酯进行皂化,聚氧亚烷基醚的分子中含有通式[I]所代表的结构单元:
其中 R' 和 R2 分别代表在其主链上具有 2 至 5 个碳原子的亚烷基,该亚烷基可被低级烷基或低级烷氧基取代;t 为 0 或 1 的整数;m 和 n 分别代表 0 或 1 至 10 的整数;且 I + m + n > 2;
有机(脂肪族或芳香族)磺酸催化剂,在有水存在的高温下进行。与传统的以酸为催化剂的水解工艺相比,该工艺能以更高的反应速率生产出皂化度更高的聚乙烯醇。
