Quantitative determination of absorption and first-pass metabolism of apicidin, a potent histone deacetylase inhibitor.

Shin BS1, Yoo SD, Kim TH, Bulitta JB, Landersdorfer CB, Shin JC, Choi JH, Weon KY, Joo SH, Shin S.Author information 1College of Pharmacy, Catholic University of Daegu, Gyeongsan-si, Gyeongbuk, South Korea (B.S.S., J.C.S., J.H.C., K.Y.W., S.H.J.); School of Pharmacy, Sungkyunkwan University, Suwon, Gyeonggi-do, South Korea (S.D.Y., T.H.K.); Centre for Medicine Use and Safety, Monash University, Parkville, Australia (J.B.B., C.B.L.); Department of Pharmacy, Institute of Pharmaceutical Research and Development, College of Pharmacy, Wonkwang University, Iksan, Jeonbuk, South Korea (S.S.).AbstractApicidin, a potential oral chemotherapeutic agent, possesses potent anti-histone-deacetylase activity. After oral administration, the total bioavailability of apicidin is known to be low (14.2%-19.3%). In the present study, we evaluated the factors contributing to the low bioavailability of apicidin by means of quantitative determination of absorption fraction and first-pass metabolism after oral administration. Apicidin was given to rats by five different routes: into the femoral vein, duodenum, superior mesenteric artery, portal vein, and carotid artery. Especially, the fraction absorbed (FX) and the fraction that is not metabolized in the gut wall (FG) were separated by injection of apicidin via superior mesenteric artery, which enables bypassing the permeability barrier. The FX was 45.9% ± 9.7%, the FG was 70.9% ± 8.1% and the hepatic bioavailability (FH) was 70.6% ± 12.3%, while the pulmonary first-pass metabolism was minimal (FL = 102.8% ± 7.4%), indicating that intestinal absorption was the rate-determining step for oral absorption of apicidin. The low FX was further examined in terms of passive diffusion and transporter-mediated efflux by in vitro immobilized artificial membrane (IAM) chromatographic assay and in situ single-pass perfusion method, respectively. Although the passive diffusion potential of apicidin was high (98.01%) by the IAM assay, the in situ permeability was significantly enhanced by the presence of the P-glycoprotein (P-gp) inhibitor elacrider. These data suggest that the low bioavailability of apicidin was mainly attributed to the P-gp efflux consistent with the limited FX measured in vivo experiment.

Premature and severe cardiovascular disease in a Mexican male with markedly low high-density-lipoprotein-cholesterol levels and a mutation in the lecithin:cholesterol acyltransferase gene: A family study.

Lecithin:cholesterol acyltransferase (LCAT) is a key enzyme in the formation, maturation and function of HDL. Therefore impaired LCAT function may enhance atherosclerosis because of defective cholesterol transport. In this study, we examined a 34-year old LCAT‑deficient patient and eight first-degree family members. There was a strong family history for CVD and type 2 diabetes mellitus (DM2). The proband was found homozygous for a previously reported LCAT gene mutation (Thr37Met). A sister and two sons of the proband were heterozygous for the same mutation. The proband had DM2 and showed severe multivessel coronary artery disease, corneal opacification and extremely low HDL-C levels. Large HDL particles were absent while small HDL particles were increased. The HDL of the patient had a reduced ability to promote cell cholesterol efflux, and the low‑density lipoproteins (LDL) were more susceptible to oxidation. Among his family members, two heterozygotes and one non-carrier had early carotid or coronary atherosclerosis. In conclusion, as the increased LDL oxidability and structural and functional abnormalities of HDL particles have been reported in patients with obesity and diabetes, the results suggested that the adverse coronary risk profile, and not being LCAT deficient, may be responsible for the CVD found in our proband, and for the early atherosclerosis observed in the two heterozygotes and in the wild‑type family members.
