In a continuing structure-activity relationship study of potent anti-HIV agents, seven new triterpene derivatives were designed, synthesized, and evaluated for in vitro antiviral activity. Among them, moronic acid derivatives 19, 20, and 21 showed significant activity in HIV-1 infected H9 lymphocytes. Compounds 19 and 20 were also evaluated against HIV-1 NL4-3 and drug resistant strains in the MT-4 cell line. Compounds 19 and 20 showed better antiviral profiles than the betulinic acid analogue 8 (PA-457), which has successfully completed a Phase IIa clinical trial. Compound 20 showed potent anti-HIV activity with EC50 values of 0.0085 muM against NL4-3, 0.021 muM against PI-R (a multiple protease inhibitor resistant strain), and 0.13 muM against FHR-2 (an HIV strain resistant to 8). Promising compound 20 has become a new lead for modification, and further development of 20-related compounds as clinical trial candidates is warranted.

We newly synthesized well-crystallized hydrotalcite-supported copper nanoparticles, denoted as Cu/HT(c), which acted as a highly efficient heterogeneous catalyst for oxidant-free lactonization of various diols under liquid-phase conditions. The Cu/HT(c) catalyst could be recovered by simple filtration and reused without the significant loss of its activity and selectivity.

Electric Literature of 52079-23-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52079-23-9, (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, introducing its new discovery.

A highly modular and stereoselective synthesis of tetrasubstituted helical alkenes is accomplished by a Pd-catalyzed norbornene-mediated domino reaction. This protocol features the rapid assembly of four C-C bonds via sequential C-H activations and carbopalladations along with efficient access to enantiopure bromoalkyl aryl alkyne precursors using homologative alkynylation as the key transformation. Three distinct elements of stereoselectivity were observed in the preparation of the chiral helical alkenes: retention of stereochemistry of the substrates, induced helical diastereoselectivity in the alkene formation, and the exclusive exo-facial selectivity of the norbornene incorporation.

The interaction of two IR chromophores yields a strong vibrational circular dichroism couplet whose sign reflects the absolute configuration of the molecule. We present a method to determine absolute configuration of a chiral molecule based on this couplet without need of theoretical calculation. Not only can this method analyze various molecules whose absolute configuration is difficult to determine by other spectroscopic methods, but also it can significantly enhance VCD signals.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Transition metal ion-assembled three-helix bundle proteins provide templates to investigate the thermodynamic and dynamic structural consequences of the deletion of a single backbone hydrogen bond from an I±-helical architecture. This deletion does not perturb the steady-state secondary structure of the protein as measured by circular dichroism spectroscopy but does decrease the overall folding free energy by ca. 0.7 kcal/mol. We have used intraprotein electron transfer as a measure of the structure-sensitive dynamics of our system. The deletion of a single hydrogen bond in one of the helices of a three-helix bundle does not significantly change the measured electron-transfer rate. This is in agreement with “Greenpath” electron-transfer pathway calculations, which assume a constant and invariant structure for the architecture. Given the exponential dependence of electron-transfer rate on distance and that fluctuations in the intervening secondary structure will cause variations in electron donor-acceptor distances, the measured electron-transfer rate associated with hydrogen bond deletion allows us to calculate a differential dynamic structural fluctuation associated with hydrogen bond deletion of less than 0.6 AI¿ over the millisecond time scale of the experiment.

Complementary chemistry: A one-pot method for the site-selective alkylation of arenes controlled by steric effects is reported. The process occurs through Ir-catalyzed C-H borylation, followed by Pd- or Ni-catalyzed coupling with alkyl electrophiles. This selectivity complements that of the typical Friedel-Crafts alkylation; meta-selective alkylation of a broad range of arenes with various electronic properties and functional groups occurs in good yield with high site selectivity.

Here we report the synthesis and evaluation of antiplasmodial activity of a novel series of bicyclic peroxides inspired by the marine natural compound dihydroplakortin. We developed a synthetic strategy leading to the dihydroplakortin-related peroxides in only a few steps. The in vitro antiplasmodial potency of the peroxides was similar to, or greater than, that of the reference natural compound, and structure-activity relationship studies revealed several key structural requirements for activity and potency.
