The pentasaccharide moiety of thornasteroside A, the first asterosaponin isolated from starfish, has been synthesized for the first time
A new synthetic route to hainanolidol and harringtonolide offers flexibility to access other members of Cephalotaxus norditerpenes
A new method has been developed to selectively hydrogenate imine bonds by using an iridium complex
Benzannulation of phthalic anhydrides with alkynes to polyfunctionalized naphthalenes and phenanthrenes was confirmed to be straightforward using a palladium catalytic system. Sequential liberation of CO2 and CO occurred via oxidative decomposition of anhydride. In the case of 1,8-naphthalenedicarboxylic anhydrides, both aryls were encompassed in the annulation reaction to afford acenaphthylenes.

New Drug Discovery from natural products
A cough is a response of the physique to irritants affecting the respiratory system. It is normally outlined as the unexpected act of expelling air from the lungs with a sharp sound. It can be a deliberate or involuntary act. Generally, it is the body&rsquos way of expelling bacteria and should not be suppressed

In addition, keep a wholesome life style, stay away from tobacco ingestion, and use filtered masks in locations where there may possibly be heavy pollution.
In the present article, we describe SAR studies within a series of N-hydroxy-dihydronaphthyridinone HIV integrase inhibitors that led to a candidate compound, PF-4776548, of high potency and with an excellent resistance profile. Uncertainties around the human pharmacokinetic predictions for PF-4776548 led to the compound being taken into a human microdose study to confirm its human pharmacokinetics, the results of which are described herein.
