✦ Synopsis

Several two-dimensional NMR techniques were applied to assign completely the ' H and 13C chemical shifts and to study the configuration and conformation of a new triterpenoid, 3-keto-9,10,19cyclopropyllanost-24-en-26-oic acid (ganwuweizic acid). Some 13C NMR signals previously reported for the triterpenoid skeleton were corrected.

British anti-lewisite (2,3-dimercaptopropanol) (BAL) has long been used as an arsenic antidote, but its therapeutic efficacy is limited by its inherent toxicity. Two less toxic potential replacements for BAL are dimercaptosuccinic acid and dimercaptopropanesulfonic acid. These two disulfhydryl compo
