Duocarmycin-based prodrugs for cancer prodrug monotherapy

The synthesis and biological evaluation of novel prodrugs based on the cytotoxic antibiotic duocarmycin SA (1) for a selective treatment of cancer using a prodrug monotherapy (PMT) are described. Transformation of the phenol 8 with the glucuronic acid benzyl ester trichloroacetimidate 9b followed by reaction with DMAI·HCl (10) gives the glucuronide 11b, which is deprotected to afford the desired prodrug 4a containing a glucuronic acid moiety. In addition, the prodrug 4b with a glucuronic methyl ester unit is prepared. The cytotoxicity of the glucuronides is determined using a HTCFA-assay with IC50 values of 610 nM for 4a and 3300 nM for 4b. In the presence of beta-glucuronidase, 4a expresses an IC50 value of 0.9 nM and 4b of 2.1 nM resulting in QIC50 values of about 700 for 4a and 1600 for 4b.

Glucuronide and sulfate conjugates of ICI 182,780, a pure anti- estrogenic steroid. Order of addition, catalysis and substitution effects in glucuronidation

The 3-sulfate 4 and 3- and 17-glucuronide conjugates 5 and 6 of the pure anti-estrogenic steroid ICI 182,780 1, which is expected to be an effective agent for the treatment of breast cancer, have been prepared. The synthesis of 6 could only be satisfactorily achieved using an inverse addition technique, not previously employed in the glucuronic acid series: the value of this technique for some other aglycones is discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 92420-89-8, you can also check out more blogs about92420-89-8

Flavonoid metabolism: The synthesis of phenolic glucuronides and sulfates as candidate metabolites for bioactivity studies of dietary flavonoids

Epidemiological studies indicate that flavonoid intake is inversely associated with the risk of coronary heart disease, yet the mechanisms responsible for their bioactivity are still a matter of debate. Based on the rapid and extensive metabolism of most flavonoids, their health effects most likely result from the biological activity of their metabolites. However, a lack of commercially available compounds/standards has prevented the study of metabolite bioactivity and resulted in a focus on non-physiologically relevant precursor/parent structures. This paper details the synthesis of a series of phenolic glucuronide 1a-e and sulfate 2a-e derivates as candidate metabolites for use as reference compounds in metabolic profiling studies and for the exploration of flavonoid bioactivity.

3-[(1 S,2 S,3 R)-2,3-Difluoro-1-hydroxy-7-methylsulfonylindan-4-yl]oxy-5-fluorobenzonitrile (PT2977), a Hypoxia-Inducible Factor 2alpha (HIF-2alpha) Inhibitor for the Treatment of Clear Cell Renal Cell Carcinoma

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.

Synthetic oligosaccharide constructs exhibiting tailored and well-defined heparan sulfate (HS) like sequences offer the potential to modulate dynamic HS-dependent biomolecular recognition processes. We report an efficient strategy for the generation of HS-like fragments [GlcA-beta-(1,4)-GlcNAc] and related dimerized (gemini) disaccharides (4a and 4b) via n-pentenyl glycoside formation. When a convergent synthetic approach was utilized, construction of target molecules was achieved through a combination of chemoselective protection/deprotection protocols, imidate and n-pentenyl glycosylations, and functional group manipulations followed by ozonolysis and reductive amination. For example, glycosylation of a 2-azido glycoside (25) with a trichloroacetimidate glucuronic acid donor (13), using a catalytic amount of TMSOTf, furnished heparin-like disaccharides (28a and 28b) that were equipped with an n-pentenyl tether at the anomeric end. In turn, heparinoid-like gemini disaccharides (4a and 4b) were produced by selective transformation of the olefinic unit in the n-pentenyl glycoside to the four-carbon aldehyde followed by reductive amination with ethylene-diamine. The described synthetic approach provides access to structural variants of small heparinoid oligomers as versatile building blocks for generating novel HS mimetic pharmacotherapeutics, diagnostic reagents, and biomaterials.

Betaglycan, also known as TGF-beta type III receptor, is a membrane-anchored proteoglycan, which has two glycosaminoglycan (GAG) attachment sites (Lo?pez-Casillas, F.; Payne, H. M.; Andres, J. L.; Massague?, J. J. Cell Biol. 1994, 124, 557-568). Chondroitin sulfate (CS) or heparan sulfate (HS) can attach to the first site, Ser535, whereas only CS attaches to the second, Ser546. Although the mechanism behind the assembly of CS and HS is not fully understood, it has been reported that the assembly of HS requires not only a cluster of acidic residues but also hydrophobic residues located near the Ser-Gly attachment sites (Esko, J. D. Zhang, L. Curr. Opin. Struct. Biol. 1996, 6, 663-670). To further understand the effects of amino acids close to the Ser residues of the GAG-attachment sites on the glycosyltransferases, two tetraosyl peptides derived from the CS attachment sites of betaglycan, GlcA-Gal-Gal-Xyl-SerGlyAspAsnGly (1) and GlcA-Gal-Gal-Xyl-SerGlyAspAsnGlyPheProGly (2), were synthesized, and used as donor substrates for beta1,4-N-acetylgalactosaminyltransferase-I (beta4GalNAcT-I) and alpha1,4-N-acetylglucosaminyltransferase-I (alpha4GlcNAcT-I). Both the chemically synthesized linkage region tetrasaccharides were far better acceptors for beta4GalNAcT-I than for alpha4GlcNAcT-I in vitro, although they also showed appreciable acceptor activity for alpha4GlcNAcT-I.

Enzymatic glycosidation using sugar oxazolines 1-3 having a carboxylate group as glycosyl donors and compounds 4-6 as glycosyl acceptors was performed by employing a chitinase from Bacillus sp. as catalyst. All the glycosidations proceeded with full control in stereochemistry at the anomeric carbon of the donor and regio-selectivity of the acceptor. The N,N?-diacetyl-6?-O- carboxymethylchitobiose oxazoline derivative 1 was effectively glycosidated, under catalysis by the enzyme, with methyl N,N?-diacetyl-beta- chitobioside (4), pent-4-enyl N-acetyl-beta-d-glucosaminide (5), and methyl N-acetyl-beta-d-glucosaminide (6), affording in good yields the corresponding oligosaccharide derivatives having 6-O-carboxymethyl group at the nonreducing GlcNAc residue. The N,N?-diacetyl-6-O-carboxymethylchitobiose oxazoline derivative 2 was subjected to catalysis by the enzyme catalysis; however, no glycosidated products were produced through the reactions with 4, 5, and 6. Glycosidation reactions of the beta-d-glucosyluronic-(1?4)-N-acetyl-d- glucosamine oxazoline derivative 3 proceeded with each of the glycosyl acceptors, giving rise to the corresponding oligosaccharide derivative having a GlcA residue at their nonreducing termini in good yields.
