Disease relevance of Lykurim

  • When 10 rats with hepatoma 8999 were treated 15 times with the optimal dose of Lycurim (7.5 mg/kg every 10 1/2 days), 1-year survivors numbered 7 [1].
  • Alternate doses of Lycurim (7.5 mg/kg) and PF (3 mg/kg) at 5-day intervals for 4 months to 10 rats gave an ILS of 152% with eight 1-year survivors and no host toxicity [1].
  • A dose escalation study was started to determine the applicability of Lycurim in the form of high volume intraperitoneal instillation ('belly bath') for the treatment of ovarian cancer [2].
  • Evaluation of the therapeutic effect of lycurim in lymphoma [3].
  • Lycurim (NSC 122402) in the treatment of chronic lymphocytic leukemia [4].

High impact information on Lykurim

  • The more rapidly growing, less differentiated hepatoma 3924A was tenfold less sensitive to Lycurim in vitro, and three treatments in vivo (10 mg/kg given every 8 days) gave an ILS of only 18% in ACI/N rats [1].
  • Hepatoma 8999 was sensitive to Lycurim [1,4-di-(methylsulfonyloxy-ethylamino)-1,4-dideoxy-ms-erythritol] with a mean lethal dose (LD50) of 8.1 X 10(-8) M for a 6-hour treatment in vitro [1].
  • Lycurium [1,4-di-(methylsulfonyloxy-ethylamino)-1,4-didesoxy-erythrioldimethylsulfonate; R-74; NSC-122402] undergoes rapid hydrolysis in aqueous solutions [2].
  • Lycurim and PF given together in their IC50 concentrations (0.016 and 0.085 microM, respectively) yielded synergistic cell kill in 7-day treatment of proliferating cultures [5].
  • The authors treated DBA/2 mice with L1210 leukemia with cyclophosphamide (CY) plus lycurim (LY), both alkylating agents [6].

Chemical compound and disease context of Lykurim


Anatomical context of Lykurim


Analytical, diagnostic and therapeutic context of Lykurim

  • This conclusion is supported by clinical experience showing that intracavitary administration of the same amount of Lycurim causes much milder systemic side-effects than intravenous injection [2].
