During a search for a sporicidal agent to equal or surpass formaldehyde in activity, a group of saturated dialdehydes ranging from two to six carbons was discovered. These dialdehydes exerted a surprisingly high degree of activity in isopropanol buffered with a carbonate or bicarbonate. Without the proper buffer, practically no activity was observed. A solution of 1% glutaraldehyde, 0.3% NaHCO(...

Although commonly known as a highly toxic chemical, cyanide is also an essential reagent for many industrial processes in areas such as mining, electroplating, and synthetic fiber production. The "heavy" use of cyanide in these industries, along with its necessary transportation, increases the possibility of human exposure. Because the onset of cyanide toxicity is fast, a rapid, sensitive, and ...

The replication of Sarcoma 180 cells in culture was inhibited by 3,6-dihydroxy-4,5-dimethylphthalaldehyde (HMPA). The inhibition of growth caused by HMPA was evident after treatment of cells with drug for only 15 min. This exposure period caused decreased in (a) cloning efficiency, (b) transport and/or phosphorylation of [3H]thymidine and [3H]uridine, (c) incorporation of radioactive nucleoside...
