| | 10,11-methylenedioxycamptothecin Usage And Synthesis |
| Uses | FL118 (10,11-(Methylenedioxy)-20(S)-camptothecin), a Camptothecin.html" class="link-product" target="_blank">Camptothecin (HY-16560) analogue, is a potent and orally active survivin inhibitor. FL118 binds to oncoprotein DDX5 (p68) to dephosphorylates and degrades DDX5. FL118 can be used for the research of cancer[1][2]. | | in vivo | FL118 (5 and 10 mg/kg; p.o. once a week for 20 days) inhibits antitumor activity[1].
FL118 (0-1.5 mg/kg, i.p. once every other day for five times) effectively eliminates human colon and head-and-neck tumors that acquire irinotecan or topotecan resistance[4].
FL118 (1.5 mg/kg, i.v. once) exhibits favorable pharmacokinetics profiles[4].
Pharmacokinetic Parameters of FL118 in female SCID mice[4].
| Sample | FaDu | SW620 | Plasma | | T1/2 (hr) | 6.852 | 12.75 | 1.788 | | Tmax (hr) | 0.167 | 0.167 | 0.167 | | Cmax (ng/g, mL) | 115 | 158 | 43 | | AUC (hr*ng/g) | 413 | 842 | 82 | | AUC∞ (hr*ng/g) | 448 | 897 | 104 | | AUC% Extrap (%) | 7.74 | 6.17 | 21.7 | | Vz (g/kg) (ml/kg) | 33052 | 30742 | 36849 | | Cl (g/hr/kg) (ml/hr/kg) | 3343 | 1671 | 14287 |
| Animal Model: | Fmale BALB/c nude mice[1] | | Dosage: | 5 and 10 mg/kg | | Administration: | Oral gavage; 5 mg/kg for once a week; 10 mg/kg for once a week; for 20 days | | Result: | Showed better antitumor activity than topotecan and dose-dependenly suppressed the growth of ES-2 tumors by upregulating the expression level of CYGB. |
| Animal Model: | SCID (severe combined immunodeficiency) mice bearing human SW620 (colon) and FaDu (head-and-neck) xenograft tumors (ten-week-old, female, 20-25 g, 5 mice per cage)[4] | | Dosage: | 0, 0.75, 1, 1.5 mg/kg | | Administration: | IP, once every other day for five times as one cycle (If tumors relapse, mice were treated with FL118 for second or third cycles) | | Result: | Eliminated human xenograft tumors that acquired irinotecan or topotecan resistance, and was also effective after multiple cycles of treatment without the generation of FL118 resistance. |
| Animal Model: | SCID (severe combined immunodeficiency) mice bearing human SW620 (colon) and FaDu SCID mice bearing human SW620 (colon) and FaDu (head-and-neck) xenograft tumors (ten-week-old, female, 20-25 g, 5 mice per cage)[4] | | Dosage: | 1.5 mg/kg | | Administration: | IV, once | | Result: | Exhibited favorable pharmacokinetics profiles. |
