[Chapter 1. The challenges of pricing innovative drugs]
Abstract:
Several innovative drugs including the first gene therapy drugs are expected shortly. In light of the debates on the new products for the treatment of hepatitis C and cancer, this wave of innovation raises questions about the ability of our health insurance systems to bear the expense and pay the price claimed by the laboratories. This situation has led to a reflection on the criteria for setting the price of drugs. Public authorities have developed new regulatory mechanisms and have opened a debate to explore new rules that would take into account - in the construction of contracts and prices - real world evidence.

SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...
SN1 Reaction: Kinetics
However, Sir Christopher Ingold and Edward D. Hughes, who studied the kinetics of various nucleophilic substitution reactions, noticed that a tertiary alkyl halide does undergo a nucleophilic substitution reaction in the presence of a weak nucleophile. While studying the substitution...
SN1 Reaction: Mechanism
Firstly, the haloalkane ionizes to generate a carbocation intermediate and a halide ion. This heterolytic cleavage is highly endothermic with large activation energy. The ionization of the substrate, facilitated by a...
Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
Predicting Products: SN1 vs. SN2
With increased substitution on the alkyl halide,...
