Furthermore total fluorine content was determined in selected serum samples and the metabolism of FM-3422 characterized by FINMR.

Name equest No. -h@2@Q@ -------- D a ted eport: ----------- Proi. No.21.2,@@16PL00 Reference 137-088 by IRDC was a 90 day subacute Rhesus monkey toxicity study of FM-3422. The original study was set at the following dosage 30, 100, 300, 1000 mg/kg/day. The study was revised with levels: dosage levels of 10, 30, 100, 300 mg/kg/day. It appears (see Table below) that the dosage levels were lowered again prior to the study, The serum and livers were each individually submitted for analysis. Each group contained 4 monkeys, 2 male and 2 female as follows: Group 1 IV v Dosage Level 0 1 mg/kg/day 3 11 10 to 30 Survival, 4/4 4/4 4/4 4/4 3/4 SERUM ANALYSIS @l@k e a@e@' 7470M 0 7493F 0 FM-3422 in Serum 0 0 (ppm) Total F in Serum (ppm) nmO nm 7467M 1 0 ran 7489F 1 0 nm 7469M 3 0.1 nm 7474M 3 nm 75 7487F 3 0.1 nm #6995 -2 7475M 7498F (2) Dosage 10 10 FM-3422 in Serum nm 0.4 7472M 30 0.5 7499F 30 0.7 August 16, 1978 pm) Total F in Serum (ppm) 150 nm 375 nm (DM = Male, F = Female z@In mg/kg/day (2)nm= not measured The analysis of the serum for FM-3422 indicated that this compound was present at a very low concentration. Total fluoride analysis indicated the presence of a significant level of fluoride. Therefore the serum of 7472M was prepared for F/NMR analysis. The NMR spectra indicated (Richard Newmark) the presence of.FC-95 with no other significant fluorine peak noted. A very high branched content was observed (80% branched/20% linear). The branched/linear ratio of FM-3422 used in the feeding study was found to be 40% branched/60% linear. Perhaps the branched isomer is retained to a greater extent than the linear. The fact that a high level of FC-95 was found in the serum and essentially no FM-3422, indicates that FM-3422 is metabolized to the sulfonic acid. Furthermore, the study would indicate that FM-3422 is cleared from the body rather rapidly, that is before it is completely converted to FC-95 since the monkey tolerates FM-3422 at concentrations approximately 10 times greater than FC-95; this suggests that FC-95 builds up slowly with time.

The data shows that the female accumulates and/or retains FM-3422 at a level 2 to 3 times higher than the rrele. In addition, the.only animal to die during the study was a female, perhaps again suggesting a greater sensitivity of the female to this compound. IODN Belisle jz
