and 9b, were prepared as reported in the ref3). The other pivaloyloxymethyl esters, 9c, 9d and 9e, were prepared via another procedure, which is shown in Scheme 2. Other esters llp~ llw were prepared in the manner similar to that of 9e from the sodium salt of 5e and the corresponding halides. The latter halides were prepared from chloromethyl chlorosulfate (or chloromethyl iodide) and the corre-
متن کاملMetabolism of D-cephaloglycin-14C and L-cephaloglycin-14C in the rat.
The fate of the orally effective antibiotic D-cephaloglycin and its much less active L-enantiomer has been studied in the rat. D-Cephaloglycin-14C is metabolized by two pathways, (1) hydrolysis of the amide linkage to form D-2-phenylglycine-14C and (2) deacetylation to form deacetyl-D-cephaloglycinUC. D-Cephaloglycin is absorbed from the gastro-intestinal tract at least in part as the intact an...
متن کاملAliskiren: A Novel, Orally Active Renin Inhibitor
Renin-angiotensin-aldosterone systems play a major role in the regulation of human homeostasis mechanism, which are also involved in the development of hypertension and end-organ damage through activation of angiotensin II. Inhibitors of the renin-angiotensin-aldosterone system may reduce the development of end-organ damage to a greater extent than other antihypertensive agents. Aliskiren is th...
متن کاملAn orally active inhibitor of renin.
A potent renin inhibitor, U-71038 (Boc-Pro-Phe-N-MeHis-Leu psi[CHOHCH2]Val-Ile-Amp), was tested for oral effectiveness. Enzyme kinetic studies indicated that U-71038 was a competitive inhibitor of hog renin with an inhibitor constant (Ki) value of 12 nM. Intravenous as well as oral administration of U-71038 to anesthetized, ganglion-blocked rats infused with hog renin elicited dose-related hypo...
متن کاملCefroxadine (CGP-9000), an orally active cephalosporin.
Cefroxadine (GCP-9000; CXD), 7 beta[D-2-amino-2-(1,4-cyclohexadienyl)-acetamido]-3-methoxy-ceph-3-em-carboxylic acid, is a new orally active cephalosporin derivative. The spectrum of antibacterial activity of CXD is identical with that of cephalexin (CEX), but CXD was twofold more effective than CEX against Escherichia coli and Klebsiella pneumoniae, CXD was as stable to penicillinase as CEX, b...
