We have recently described general methods for the synthesis of allenic nitrilcsl which rendered these compounds readily available. Some of these nitriles were intended as starting materials for the synthesis of allenic acids, acid chlorides, esters and amides in connection with our progranrme ou bi

~:
O~ 'clarion of natural and synthetic pheora~laninm with alkaline H202 at room temperature led to the formation of a major product (up to 25% yield w/w) which was identified as the novel 2carboxy-4-hydroxy-6-(2 -amino-2 -ยข8rboxyethyl)benzothiaTole ( 6).

To study the mechanisms of chondrocyte damage, chondrocyte cytotoxicity as shown by chromium-51 release induced by polymorphonuclear leukocytes (PMNLs) was examined. PMNLs significantly enhanced chondrocyte cytotoxicity in the presence of phorbol dibutyrate. This chondrocyte damage was abolished by
Lactose, maltose, cellobiose, and galactose can be degraded selectively in one step and in high yield into the corresponding next lower aldose and formic acid by H202 in the presence of borate. The selectivity further improves when a small amount of EDTA is added, in order to suppress the influence
