| In Vitro | CI-994 (N-acetyldinaline) is a novel oral compound with a wide spectrum of antitumor activity in preclinical models. The mechanism of action may involve inhibition of histone deacetylation and cell cycle arrest. CI-994 is combined with antineoplastic agents commonly used in non-small cell lung cancer cell line management, a marked synergism of action (R=1.8, R=1.5) is observed between CI-994 (40 μM) and gemcitabine (0.01 μM) at 48 and 72 h of treatment[2].CI-994 inhibits mitogen-stimulated blood lymphocyte proliferation with an IC50 value of 3 μM[4]. |
| In Vivo | CI-994 has activity against 8/8 solid tumors tested: pancreatic ductal adenocarcinoma #02 (4.7); pancreatic adenocarcinoma #03 (3.0; 1/6 cures); colon adenocarcinoma #38 (1.6); colon adenocarcinoma #51/A (1.1); mammary adenocarcinoma #25 (1.7); mammary adenocarcinoma #17/ADR (0.5); Dunning osteogenic sarcoma (4.0); and the human prostate carcinoma LNCaP (1.2). CI-994 is the acetylated metabolite of dinaline and has the same spectrum of activity in vivo as dinaline. It also behaves similarly in schedule comparison/toxicity trials[3]. CI-994 can effect lymphoid tissue in rats within 1 day of a single oral dose, that effects are generally reversible within 7 days[4]. |
| Animal Admin | Rats: To characterize the effects of CI-994 on lymphoid tissue, male rats are administered single oral doses at 0 (vehicle control), 10, 23, and 45 mg/kg and killed up to 7 days after dosing for evaluation of white blood cell differentials, bone marrow differentials, lymphoid tissue weights, and selected histopathology of lymphoid tissue[4]. |
