Heterospirocyclic N-(2H-azirin-3-yl)-L-prolinates: New dipeptide synthons

The synthesis of methyl N-(1-aza-6-oxaspiro[2.5]oct-1-en-2-yl)-L-prolinate (1e) has been performed by consecutive treatment of methyl N-[(tetrahydro-2H-pyran-4-yl)thiocarbonyl]-L-prolinate (5) with COCl2, 1.4-diazabicyclo[2.2.2]octane (DABCO), and NaN3 (Scheme 1). As the first example of a novel class of dipeptide synthons, 1e has been shown to undergo the expected reactions with carboxylic acids and thioacids (Scheme 2). The successful preparation of the nonapeptide 16, which is an analogue of the C-terminal nonapeptide of the antibiotic Trichovirin I IB, proved that 1e can be used in peptide synthesis as a dipeptide building block (Scheme 3). The structure of 7 has been established by X-ray crystal-structure analysis (Figs. 1 and 2).

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.name: Tetrahydro-2H-pyran-4-carbonyl chloride, you can also check out more blogs about40191-32-0

Synthesis of 3,3?-neotrehalosadiamine and related 1,1?-aminodisaccharides using disarmed, armed, and superarmed building blocks

Here we report a high yielding, stereoselective synthesis of the naturally occurring 1,1?-disaccharide neotrehalosadiamine (NTD) and some related analogs. Following an eleven-step sequence, seven of which did not require chromatographic separation, NTD was generated in 60% overall yield from the inexpensive, commercially available precursor 1,2:5,6-di-O-isopropylidene- alpha-delta-glucofuranose. The key a,b-linkage of NTD was formed in a highly stereoselective manner by taking advantage of the participating effect of the acyl group at O-2 of the donor glycoside. The influence of electronic effects of disarmed, armed, and superarmed glycosyl donors and acceptors on the outcome of 1,1?-glycosidation was also observed. Antibacterial studies using NTD and its analogs show detectable but weak antistaphylococcal activity.

The Discovery of in Vivo Active Mitochondrial Branched-Chain Aminotransferase (BCATm) Inhibitors by Hybridizing Fragment and HTS Hits

The hybridization of hits, identified by complementary fragment and high throughput screens, enabled the discovery of the first series of potent inhibitors of mitochondrial branched-chain aminotransferase (BCATm) based on a 2-benzylamino-pyrazolo[1,5-a]pyrimidinone-3-carbonitrile template. Structure-guided growth enabled rapid optimization of potency with maintenance of ligand efficiency, while the focus on physicochemical properties delivered compounds with excellent pharmacokinetic exposure that enabled a proof of concept experiment in mice. Oral administration of 2-((4-chloro-2,6-difluorobenzyl)amino)-7-oxo-5-propyl-4,7-dihydropyrazolo[1,5-a]pyrimidine-3-carbonitrile 61 significantly raised the circulating levels of the branched-chain amino acids leucine, isoleucine, and valine in this acute study.

The metabolism of clopidogrel is catalyzed by human cytochrome P450 3A and is inhibited by atorvastatin

The prodrug clopidogrel (Plavix) is activated by cytochrome P450 (P450) to a metabolite that inhibits ADP-induced platelet aggregation. Clopidogrel is frequently administered to patients in conjunction with the CYP3A4 substrate atorvastatin (Lipitor). Since clinical studies indicate that atorvastatin inhibits the antiplatelet activity of clopidogrel, we investigated whether CYP3A4 metabolized clopidogrel in vitro. Microsomes prepared from dexamethasone-pretreated rats metabolized clopidogrel at a rate of 3.8 nmol min-1 nmol of P450-1, which is 65 and 1270% faster than the rate of metabolism by microsomes from control and beta-napthoflavonetreated rats, respectively. To identify the human P450s responsible for clopidogrel oxidation, genetically engineered microsomes containing a single human P450 isozyme were tested for their ability to oxidize clopidogrel. CYP3A4 and 3A5 metabolized clopidogrel at a significantly higher rate than eight other P450 isozymes, suggesting that CYP3A4 and 3A5 are primarily responsible for in vivo clopidogrel metabolism. Clopidogrel interacts with human CYP3A4 with a spectral dissociation constant (Ks), Km, and Vmax of 12 muM, 14 ¡À muM and 6.7 ¡À 1 nmol min-1 nmol P450-1, respectively. Atorvastatin lactone, the physiologically relevant substrate, inhibits clopidogrel with a KI of 6 muM. When clopidogrel and atorvastatin are present at equimolar concentrations, clopidogrel metabolism is inhibited by greater than 90%. Since CYP3A4 and 3A5 metabolize clopidogrel faster than other human P450 isozymes and are the most abundant P450s in human liver, they are predicted to be predominantly responsible for the activation of clopidogrel in vivo.
