The Chen Synthesis of (-)-Nakiterpiosin
Chemexpress (-)-Nakiterpiosin (3), isolated from the thin encrusting sponge Terpios hoshinota, has an IC50 against murine P388 leukemia cells of 10 ng/mL. Chuo Chen of UT Southwestern Medical Center developed (J.…
The Nicolaou Synthesis of (+)-Hirsutellone B
(+)-Hirsutellone B (3), isolated from the insect pathogenic fungus Hirsutella nivea BCC 2594, shows good activity (MIC = 0.78 μg/mL) against Mycobacterium tuberculosis. Approaching the synthesis of 3, K. Val-cit-PAB-OH…
The Corey Synthesis of (+)-Lupeol
The total synthesis of lupeol was one of the crowning achievements of the Robinson annulation/reductive alkylation approach to stereocontrolled polycarbocyclic construction developed by Gilbert Stork (J. Am. Chem. Soc. 1971,…
The Overman Synthesis of Briarellin F
Briarellin F (4) is an elegant representative of the complex polycyclic ethers produced by soft corals such as Briareum abestinum. Larry E. Overman of the University of California, Irvine developed…
The Williams Synthesis of (-)-4-Hydroxydictyolactone
(-)-4-Hydroxydictyolactone (3), representative of the cyclononene xenicanes isolated from the Dictyotacae algae, readily isomerizes thermally to the more stable (Z)-6,7-isomer. Attempts to directly form this strained ring system appeared to…
Biocatalytic Asymmetric Hydrogen Transfer
Bioreductions and biooxidations, although they can be highly selective, have often been limited by the requirement for expensive reducing or oxidizing biological cofactors. PMID:23626759 Wolfgang Kroutil of the University of…
The Dixon Synthesis of (-)-Nakadomarin A
(-)-Nakadomarin A (4), isolated from the sponge Amphimedon sp. off the coast of Okinama, shows interesting antifungal and antibacterial activity. The key step in the total synthesis of 4 reported…
Not be attributed to apoptosis resistance (Figure 2F). With each other these data
Not be attributed to apoptosis resistance (Figure 2F). Collectively these information suggest that the accumulation of DKO HSCs is likely to become a outcome of cell divisions that pretty much…
LDL-c contents, but have much less impact on TGs and HDL-c levels.
LDL-c contents, but have significantly less influence on TGs and HDL-c levels. Indeed, TGs concentrations had been significantly larger, but only in the postmenopausal diabetic girls when compared using the…
