Following regioselective protection of the estrogen receptor downregulator fulvestrant (ICI 182,780) 1 as its 17-acetate 2 or 3-benzoate 4, the 3-sulfate 5 and 3- and 17-glucuronide conjugates 8 and 12 were prepared. Satisfactory preparation of 12 required use of the tri-O-isobutyryl imidate derivative 10 in conjunction with an inverse-addition technique not previously employed in glucuronidation. The value of this method for simpler aglycones is discussed together with a study of variations in donor acyl substituent and catalyst. Another putative metabolite, the 17-ketone 19, was prepared by direct oxidation of 1.

The hypoxia-inducible factor 2alpha (HIF-2alpha) is a key oncogenic driver in clear cell renal cell carcinoma (ccRCC). Our first HIF-2alpha inhibitor PT2385 demonstrated promising proof of concept clinical activity in heavily pretreated advanced ccRCC patients. However, PT2385 was restricted by variable and dose-limited pharmacokinetics resulting from extensive metabolism of PT2385 to its glucuronide metabolite. Herein we describe the discovery of second-generation HIF-2alpha inhibitor PT2977 with increased potency and improved pharmacokinetic profile achieved by reduction of phase 2 metabolism. Structural modification by changing the geminal difluoro group in PT2385 to a vicinal difluoro group resulted in enhanced potency, decreased lipophilicity, and significantly improved pharmacokinetic properties. In a phase 1 dose-escalation study, the clinical pharmacokinetics for PT2977 supports the hypothesis that attenuating the rate of glucuronidation would improve exposure and reduce variability in patients. Early evidence of clinical activity shows promise for PT2977 in the treatment of ccRCC.

Introducing a new discovery about 92420-89-8, Name is (2S,3S,4S,5R,6R)-2-(Methoxycarbonyl)-6-(2,2,2-trichloro-1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate, Synthetic Route of 92420-89-8.

The antitumor activities of several glucuronide methyl esters of podophyllum derivatives were tested in vitro against two human tumor cell lines and their drug resistant sublines. The most active compound studied was methyl (4′-carbobenzoxy-4′-demethyl- epipodophyllotoxin-D-glucopyranoside)uronate 19. Compound 19 was as potent in a colon carcinoma model and was twice as potent in a lung carcinoma model as etoposide 6. In vivo, however, in a mouse leukemia P388 model, it had only marginal activity, with a maximum T/C% value of 125 at 37 mg/kg (iv).

A practical synthesis of beta-D-GlcA-(1?3)-beta-D-Gal-(1?3)-beta-D-Gal-(1?4)- beta-D-Xyl-(1?OMe) was achieved by coupling of methyl 2,3,4-tri-O-acetyl-alpha-D-glucopyranosyluronate trichloroacetimidate with a trisaccharide acceptor. The trisaccharide acceptor was obtained by condensation of 3-O-allyl-2,4,6-tri-O-benzoyl-beta-D-galactopyranosyl-(1?3)-2,4,6- tri-O-benzoyl-alpha-D-galactopyranosyl trichloroacetimidate with methyl 2,3-di-O-benzoyl-beta-D-xylopyranoside, followed by deallylation. The beta-(1?3)-linked disaccharide was prepared readily with p-methoxyphenyl 3-O-allyl-2,4,6-tri-O-benzoyl-beta-D-galactopyranoside as the key synthon. The alpha-(1?3)-linkage was formed in considerable amount with galactose mono- and disaccharide trichloroacetimidate donors with C-2 neighboring group participation.

An efficient strategy has been designed for the preparation of synthetic mimics of hyaluronan (HA, 1) and its dimerized (Gemini) disaccharides (2a,b) via n-pentenyl glycoside formation. Construction of the target molecules was achieved through a combination of protection/deprotection protocols, imidate glycosylation methodology followed by ozonolysis, and reductive amination. These tailored synthetic mimics could act as versatile building blocks with therapeutic applications in tissue engineering, treatment of cancer and as drug delivery agents.
