در ادبیات اقتصادی به ویژه اقتصاد بینالملل، اثر هاربرگر- لارسن و متذلر که به اختصار اثر hlm نامیده میشود، از اهمیت خاصی برخوردار است. طبق اثر hlm ، بدتر شدن رابطه مبادله منجر به بدتر شدن حساب جاری شده که سازوکار این تأثیرگذاری از طریق درآمد ملی است. هدف این پژوهش، بررسی اثر مذکور برای اقتصاد ایران است. متغیرهای منتخب تحقیق که به صورت سالانه هستند، عبارتند از: حساب جاری(خالص صادرات)، راب...
Mycophenolic acid (MPA), the active metabolite of the immunosuppressant mycophenolate mofetil is primarily metabolized by glucuronidation. The nature of UDP-glucuronosyltransferases (UGTs) involved in this pathway is still debated. The present study aimed at identifying unambiguously the UGT isoforms involved in the production of MPA-phenyl-glucuronide (MPAG) and MPA-acylglucuronide (AcMPAG). A...
Cell differentiation increases UDP-glucuronosyltransferase (UGT) gene expression in Caco-2 cells. Glucuronidation of 13 UGT substrates, 1-naphthol, diclofenac, epitestosterone, estradiol, ethinylestradiol, indomethacin, oxazepam, R- and S-propranolol, propofol, testosterone, trifluoperazine, and zidovudine, were studied to derive a broad view on the effect of cell differentiation on the glucuro...
OTS167 is a potent maternal embryonic leucine zipper kinase inhibitor undergoing clinical testing as antineoplastic agent. We aimed to identify the UDP-glucuronosyltransferases (UGTs) involved in OTS167 metabolism, study the relationship between UGT genetic polymorphisms and hepatic OTS167 glucuronidation, and investigate the inhibitory potential of OTS167 on UGTs. Formation of a single OTS167-...
Amlodipine is a commonly prescribed calcium channel blocker for the treatment of hypertension and ischemic heart disease. The drug is slowly cleared in humans primarily via dehydrogenation of its dihydropyridine moiety to a pyridine derivative (M9). Results from clinical drug-drug interaction studies suggest that CYP3A4/5 mediate metabolism of amlodipine. However, attempts to identify a role of...
N,N-Dipropyl-2-[4-methoxy-3-(2-phenylethoxy)phenyl]ethylamine monohydrochloride (NE-100) has been developed to treat subjects with schizophrenia. This drug is mainly excreted in the form of oxidative metabolites. In the present study, identification of p450 forms involved in the metabolism was carried out using human livers and intestinal microsomes (HLM and HIM). Eadie-Hofstee plots for NE-100...
The in vitro glucuronidation of a range of structurally diverse chemicals has been studied in hepatic and renal microsomes from human donors and the beagle dog. These studies were undertaken to improve on the limited knowledge of glucuronidation by the dog and to assess its suitability as a model species for pharmacokinetic studies. In general, the compounds studied were glucuronidated severalf...

The interaction of two ruthenium(III) complexes exhibiting high anticancer activity - namely trans-Indazolium(bisindazole) tetrachlororuthenate(III), Hlnd[RuInd(2)Cl(4)], and trans-Imidazolium (bisimidazole) tetrachlororuthenate(III), Hlm[RuIm(2)Cl(4)], - with human serum apotransferrin has been investigated through spectroscopic and chromatographic techniques with the ultimate goal of preparin...
CYP3A4 and CYP3A5 are the most important drug-metabolizing enzymes. For several drugs, heteroactivation of CYP3A-mediated reactions has been demonstrated in vitro. In vivo data suggested a possible acute activation of CYP3A4-catalyzed midazolam metabolism by efavirenz. Therefore, we aimed to investigate the effect of efavirenz on the in vitro metabolism of midazolam. The formation of 1'-hydroxy...
