Measurement of the radioactivity of [<jats:sup>14<\/jats:sup>C]oleic acid and [<jats:sup>14<\/jats:sup>C]acetate incorporated into lecithin of cells during short\u2010term incubation showed that all the inhibitors tested similarly reduced the incorporation. However, methyl mercuric chloride (MMC) was the strongest inhibitor, being effective at 4 \u03bc<jats:sc>M<\/jats:sc>, and causing more than 80% decrease at 20 \u03bc<jats:sc>M<\/jats:sc>. Inhibition by the sulfhydryl inhibitors, at less than 40 \u03bc<jats:sc>M<\/jats:sc>, ranked as follows: <jats:italic>N<\/jats:italic>\u2010ethylmaleimide &gt; \u03b1\u2010chloroacetophenone &gt; hydroquinone &gt; iodoacetamide. MMC also obstructed the enhancement by phytohemagglutinin of [<jats:sup>14<\/jats:sup>C]oleic acid incorporation into lecithin. MMC was effective at 2 \u03bc<jats:sc>M<\/jats:sc>, while the other agents had little or no effect at this concentration. Further investigation suggested that inhibition of phospholipid synthesis did no depend on reduced incorporation of oleic acid into the cellular membrane but on decreased turnover of the fatty acid into phospholipids after the incorporation. The viability of lymphocytes incubated with the agents was measured by trypan blue dye\u2010exclusion test. More than 90% of the cells treated with MMC at a concentration as low as 20\u201340 \u03bc<jats:sc>M<\/jats:sc> died, but the SH inhibitors, including NEM which greatly inhibited the phospholipid synthesis, produced few cell deaths at these concentrations. These observations show that the SH inhibitors affect enzymes in phospholipid synthesis, whereas MMC not only inhibits the enzymes but kills cells.<\/jats:p>","DOI":"10.1002\/jat.2550060111","type":"journal-article","created":{"date-parts":[[2006,10,14]],"date-time":"2006-10-14T14:44:35Z","timestamp":1160837075000},"page":"49-53","source":"Crossref","is-referenced-by-count":9,"title":["Effects of methyl mercuric chloride and sulfhydryl inhibitors on phospholipid synthetic activity of lymphocytes"],"prefix":"10.1002","volume":"6","author":[{"given":"Katsuhiro","family":"Kageyama","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuto","family":"Onoyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichi","family":"Kano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,1,11]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1080\/00039896.1970.10667210"},{"key":"e_1_2_1_3_2","first-page":"47","article-title":"Cytotoxic effects of inorganic phenyl and alkyl mercuric compounds on Hela cells","volume":"39","author":"Umeda M.","year":"1969","journal-title":"Jap.
