Experimental models for hyper-beta-lipoproteinemia were established in rats and the effects of certain hypolipidemic drugs were studied with these models. In the hyperlipemia induced in rats by feeding a high cholesterol diet, Y-9738 [ethyl 2(4-chlorophenyl)-5-ethoxy-4-oxazoleacetate] produced a dose-dependent reduction of serum cholesterol: such hypolipidemic activity was estimated to be about 7 times as great as that of clofibrate. On the other hand, clofibrate induced hepatomegaly at 100 mg/kg, whereas Y-9738 did not at this dosage, which is about 10 times the effective dose. Hyperlipemia induced by high cholesterol and thiouracil was characterized by increased beta-lipoprotein (heparin-calcium and disc electrophoresis). In this model, Y-9738 showed a dose-dependent lowering effect on beta-lipoprotein cholesterol with a marked decrease in the beta/alpha lipoprotein ratio. A tendency was noted for alpha-lipoprotein to be increased. In contrast, clofibrate exerted no effect on this hyper-beta-lipoproteinemia. These results suggest that the above models may be of value in exploring hyper-beta-lipoproteinemia and that Y-9738 may be more useful than clofibrate in the therapy of hyperlipemia.

23 patients with hyperlipidemia and hyperuricemia received acetamidoethyl-(4-chlorophenyl)-(trifluoromethylphenoxy)-acetate (halofenate), a clofibrate derivative, and probenecid or probenecid and placebo over 36 weeks following a placebo period of 6 weeks. Halofenate compared with probenecid lowered elevated serum uric acid levels satisfactorily to a therapeutic level between 5 and 6 mg/100 ml. Serum triglyceride levels were not always lowered sufficiently, serum cholesterol levels were not influenced.

With the view of examining the serum lipid metabolism-improving action of a new compound, ethyl-2-(4-chlorophenyl)-5-ethoxy-4-oxazole acetate (Y-9738), 900 mg was administered to 47 patients with various diseases associated with hyperlipidemia and/or hypo-HDL (high density lipoprotein)-emia for successive 16 weeks. Serum HDL-cholesterol increased significantly 4 weeks after the administration (mean 11.8%, p less than 0.01). In the patients with hypo-HDL-emia who showed the initial level of 50 mg/dl or less, the degree of increase was more remarkable (mean 16,4%, p less than 0.01), and a significant increase was noted until 12 weeks later. Further, a similar change was noted in respect to serum HDL-phospholipid. The main apoprotein of HDL, apoprotein A (I + II) began to increase significantly 4 weeks after the institution of the administration. At the end of the trial, it increased by mean 31% (p less than 0.01). Y-9738 did not exert any significant effect on serum total cholesterol, triglyceride and phospholipid, but it caused a reduction in so-called atherogenic indexes.

First clinical results are presented for two newly developed drugs. Both are diphenylmethane derivatives named ethyl-(+/-)-2-([alpha-(p-chlorophenyl)-p-tolyl]-oxy)-2-methylbutyrate (beclobrate, B) and (+/-)-2-(4-[(4-chlorophenyl)methyl]phenoxy)-2-methyl-butanacid-3-pyridinylmethylester (eniclobrate, E). These drugs were given in a doubleblind crossover trial with placebo periods before, in between and afterwards to 6 patients with type IIb and 13 patients with type IIa hyperlipidemia. Beclobrate was given in a dosage of 100 mg twice daily and eniclobrate in a dosage of 130 mg twice daily. Besides effectively reducing LDL-cholesterol in type IIa there was a remarkable increase in HDL-cholesterol in both types of hyperlipidemia especially for beclobrate.
