Lead-oriented synthesis: a new concept to aid drug-discovery process


 

Figure 2. a. Fragment-based screening: Small and structurally diverse molecules (circles represent functional groups) are screened for a biological target, and they are combined and modified to generate drug-like compounds. b. Diversity-oriented synthesis: Large collections of structurally diverse and complex molecules are made using a short number of reactions. The resulting compounds are optimized to produce the drug-like compounds. | Credit: P. J. Hajduk,W. R. J. D. Galloway & D. R. Spring Nature, 2011, 470, 42–43. DOI: 10.1038/470042a

 

The discovery and development of new drugs is a long and expensive process, and despite of it, essential to face present and new diseases. For small molecules, which account for the majority of the marketed drugs, the discovery process generally involves finding a starting point termed hit or lead compound. These molecules have biological activity but need to be optimized to enhance their potency and selectivity (i.e. minimize the toxicity) and improve pharmacokinetic parameters making them suitable to go to the next stage, the pre-clinical tests……….http://mappingignorance.org/2014/07/04/lead-oriented-synthesis-new-concept-aid-drug-discovery-process/

Logistics of process R&D: transforming laboratory methods to manufacturing scale

Hans-Jürgen Federsel

In the past, process R&D — which is responsible for producing candidate drugs in the required quantity and of the requisite quality — has had a low profile, and many people outside the field remain unaware of the challenges involved. However, in recent years, the increasing pressure to achieve shorter times to market, the demand for considerable quantities of candidate drugs early in development, and the higher structural complexity — and therefore greater cost — of the target compounds, have increased awareness of the importance of process R&D. Here, I discuss the role of process R&D, using a range of real-life examples, with the aim of facilitating integration with other parts of the drug discovery pipeline.

Do you want to improve efficiency and innovation in your synthetic route design, development and optimisation?

The efficient conversion of a chemical process into a process for manufacture on tonnage scale has always been of importance in the chemical and pharmaceutical industries. However, in the current economic and regulatory climate, it has become increasingly vital and challenging to do so efficiently. Indeed, it has never been so important to keep up to date with the latest developments in this dynamic field.

At this Organic Process Research & Development Conference, you will hear detailed presentations and case studies from top international chemists. The hand-picked programme of speakers has been put together specifically for an industrial audience. They will discuss the latest issues relating to synthetic route design, development and optimisation in the pharmaceutical, fine chemical and allied fields.  Unlike other conferences, practically all our speakers are experts from industry, which means the ideas and information you take home will be directly applicable to your own work.

The smaller numbers at our conferences create a more intimate atmosphere. You will enjoy plenty of opportunities to meet and network with speakers and fellow attendees during the reception, sit-down lunches and extended coffee breaks in a relaxed and informal environment. Together, you can explore the different strategies and tactics evolving to meet today’s challenges.

This is held in Pune, close proximity to Mumbai city, very convenient to stay and travel to either in Pune or Mumbai. I feel this should be an opportunity to be grabbed before the conference is full and having no room

Hurry up rush

John Knight

Dr John Knight gained a first class honours degree in chemistry at the University of Southampton, UK. John remained at Southampton to study for his PhD in synthetic methodology utilizing radical cyclisation and dipolar cyloaddition chemistry.

After gaining his PhD, John moved to Columbia University, New York, USA where he worked as a NATO Postdoctoral Fellow with Professor Gilbert Stork. John returned to the UK in 1987 joining Glaxo Group Research (now GSK) as a medicinal chemist, where he remained for 4 years before moving to the process research and development department at Glaxo, where he remained for a further 3½ years.

During his time at Glaxo, John worked on a number of projects and gained considerable plant experience (pilot and manufacturing). In 1994 John moved to Oxford Asymmetry (later changing its name to Evotec and most recently to Aptuit) when it had just 25 staff. John’s major role when first at Oxford Asymmetry was to work with a consultant project manager to design, build and commission a small pilot plant, whilst in parallel developing the chemistry PRD effort at Oxford Asymmetry.

The plant was fully operational within 18 months, operating to a 24h/7d shift pattern. John continued to run the pilot plant for a further 3 years, during which time he had considerable input into the design of a second plant, which was completed and commissioned in 2000. After an 18-month period at a small pharmaceutical company, John returned to Oxford in 2000 (by now called Evotec) to head the PRD department. John remained in this position for 6.5 years, during which time he assisted in its expansion, established a team to perform polymorph and salt screening studies and established and maintained high standards of development expertise across the department.

John has managed the chemical development and transfer of numerous NCE’s into the plant for clients and been involved in process validations. He joined Scientific Update in January 2008 as Scientific Director.

The addition of a radical to a heteroaromatic base is commonly referred to as a Minsici reaction. Such reactions constitute a broad-set of selective CH-functionalization processes. This review describes some of the major applications of Minisci reactions and related processes to medicinal or biological chemistry, and highlights some potential developments within this area.

The aim of this review is to summarize the use of Minisci reactions within medicinal chemistry, and to highlight some future opportunities to continue progression of this chemistry. As such, it is not an aim that detailed mechanistic information, or a comprehensive list of examples be described. For this, the reader is directed to excellent articles from Minisci, Harrowven and Bowman.1–3 Rather, the review is written to show that Minisci reactions are extremely valuable CH-functionalization processes within medicinal chemistry. However, their use has been somewhat under-utilized when compared with other well-known selective transformations (e.g. palladium-catalysed cross-couplings). Therefore, it is hoped that in the future, Minisci chemistry will continue to develop, such that the reactions become a staple-set of methods for medicinal and biological chemists alike.

To aid discussion, the review is divided in to several sections. First, some historical perspective is given. This is followed by a discussion of scope and limitations. The main-body of the review describes some specific examples of Minisci reactions and related processes, with a focus on their use within medicinal, or biological chemistry. Finally, brief mention is given to potential future applications, some of which may be beneficial in providing ‘high-content’ diverse libraries for screening.

The Minisci reaction is a named reaction in organic chemistry. It is a radical substitution to an aromatic compound, in particular to a heteroaromatic base, that introduces an alkyl group. The reaction was published about in 1971 by F. Minisci.[1] The aromatic compound is generally electron-deficient and with N-aromatic compounds the nitrogen atom is protonated.[2] A typical reaction is that between pyridine and pivalic acid to 2-tert-butylpyridine with silver nitrate, sulfuric acid and ammonium persulfate. The reaction resembles Friedel-Crafts alkylation but with opposite reactivity and selectivity.[3]

The Minisci reaction proceeds regioselectively and enables the introduction of a wide range of alkyl groups.[4] A side-reaction is acylation.[5] The ratio between alkylation and acylation depends on the substrate and the reaction conditions. Due to the simple raw materials and the simple reaction conditions the reaction has many applications in heterocyclic chemistry.[6][7]

Reaction between pyridine and pivalic acid to 2-tert-butylpyridine

Mechanism

A free radical is formed from the carboxylic acid in an oxidative decarboxylation with silver salts and an oxidizing agent. The oxidizing agent reoxidizes the silver salt. The radical then reacts with the aromatic compound. The ultimate product is formed by rearomatisation. The acylated product is formed from the acyl radical.[4][5]

The construction of a pilot plant constitutes an important milestone in the development cycle of a new active pharmaceutical ingredient. Pilot plants are used to gain the technological experience needed for the scale-up process and are required for producing sufficient quantities of the active pharmaceutical ingredient for clinical trials and other types of tests. As a result, even these testing facilities must comply with GMP regulations.
