Designation and justification of an Active Pharmaceutical Ingredient Starting Material (API SM) is an important aspect of the drug development and commercialization process and defines the point at which the GMP manufacturing process starts (ICH Q7: Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients). In 2014, the API SM Working Group of the International Consortium for Innovation & Quality in Pharmaceutical Development (IQ Consortium or IQ), composed of representatives from the Active Pharmaceutical Ingredient and Analytical Leadership Groups, published two manuscripts on API SMs that provided (1) a review and industry perspective of the regulatory guidances that support designation and justification of API SMs, and (2) a summary of current practices across member companies of the IQ Consortium on designation and justification of API SMs based upon a survey completed by the IQ member companies. The information and data presented in these manuscripts provided a thorough overview of current practices but more importantly revealed the absence of a universal approach within the pharmaceutical industry to justifying API SMs. Using the information from manuscript 1 and 2, this manuscript, which represents part 3 of the topic series, will provide a guiding framework that is based upon the principles described in ICH Q11 and which includes relevant experiences of the IQ member companies, for the justification of a proposed API SM to the regulatory agencies. © 2015 American Chemical Society.

The authors of this concept article are members of the IQ Green Chemistry working group, one of many subgroups of the International Consortium for Innovation and Quality in Pharmaceutical Development (IQ Consortium) which has been officially chartered in April 2010. The IQ Green Chemistry Working Group seeks to drive innovation and the awareness of green chemistry in pharmaceutical development through the establishment and adoption of best practices, sharing of information within peer networks, and collaboration with regulatory agencies and other key stakeholders. © 2013 American Chemical Society.

In the development of a new route to bendamustine hydrochloride, the API in Treanda, the key benzimidazole intermediate 5 was generated via catalytic heterogeneous hydrogenation of an aromatic nitro compound using a batch reactor. Because of safety concerns and a site limitation on hydrogenation at scale, a continuous flow hydrogenation for the reaction was investigated at lab scale using the commercially available H-Cube. The process was then scaled successfully, generating kilogram quantities on the H-Cube Midi. This flow process eliminated the safety concerns about the use of hydrogen gas and pyrophoric catalysts and also showed 1200-fold increase in space-time yield versus the batch processing. © 2013 American Chemical Society.

An efficient, catalytic hypervalent iodine-mediated oxidative 1,2-shift of 1,1′-disubstituted olefins is described. This methodology provides concise access to homobenzylic ketones with electron-donating substituents. In the case of cyclic systems, this transformation results in ring-expanded β-benzocycloalkanones, which are useful for further elaboration. © 2013 American Chemical Society.

A cost-effective one-pot synthesis of Fmoc-O-benzylphospho-l-serine, an amino acid commonly used in the synthesis of phosphorylated peptides, has been developed. Two methods for executing this synthesis are described, and both have been scaled to provide kilogram quantities of the title compound in ∼50% isolated yield. Development of both processes has led to the identification of crystallization conditions which provide the product as a solvate with high purity. An efficient process for generating the solvent-free product from the solvate has also been developed. © 2012 American Chemical Society.
