  DOI：10.1016/j.bmc.2008.11.029

  日期：2009.1

  Acylpolyamine-type spider toxins are known to be potent and specific blockers against glutamate receptors (GluRs). The present study describes the syntheses and biological activities of several fluorescent-labeled analogs related to a Madagascar Joro spider toxin NPTX-594 to analyze visually the unknown interaction between spider toxins and GluRs.

  Described is a self-indicating instant radiation dosimeter ( 1001 ) for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition ( 10 ), e.g., a diacetylene (R—C≡C—C≡C—R′, where R and R′ are substituents groups) or a radiochromic dye, a polymeric binder ( 20 ) and optionally a shelf life extender ( 50 ) or an activator ( 40 ). The radiation sensitive composition ( 10 ) changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition ( 10 ) is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.
