Understanding Medicinal Chemistry & Drug Discovery

Medicinal Chemistry is the field of scientific exploration focused on the design and discovery of new chemical compounds with therapeutic capabilities, along with their progression into beneficial medications. It encompasses the generation and fine-tuning of molecules with the goal to construct or enhance novel medicinal drugs for combating specific conditions. Drug discovery, on the other hand, signifies the mechanism through which new potential compounds are identified to serve as efficacious medications. This case entails a multifaceted sphere rooted in diverse foundational disciplines like organic chemistry, biology, and pharmacology.

New Chemical Entity (NCE)

A New Chemical Entity (NCE) refers to a medication featuring an active component that hasn’t been previously approved by the United States Food and Drug Administration (USFDA) in any other application. An NCE is typically developed by innovator drug manufacturers during the initial phase of the product development cycle. This NCE later undergoes a series of clinical trials with the aim of becoming a marketable pharmaceutical product.

“Developing and launching a new drug typically involves a time frame of 10-15 years and a financial investment exceeding $1 billion. Medicinal chemistry is pivotal in this extensive process.”

Modern Drug Discovery

Modern Drug Discovery encompasses the recognition of screening hits and the utilization of medicinal chemistry to enhance these hits. The optimization focuses on increasing the compound’s affinity, selectivity (to lessen the likelihood of side effects), efficiency/potency, metabolic stability (for an extended half-life), and oral bioavailability. The drug development process proceeds once a compound meeting all these criteria is identified. If successful, it then transition into the stage of clinical trials.

The possible impurities during the synthetic process of a therapeutic peptide include the following:

blank

Insertion

Insertion can lead to an addition of extra amino acids in the peptide chain, affecting the desired structure, function, and interaction of the synthesized peptide causing potential complications in the therapeutic uses.

blank

Deletion Sequence

During peptide synthesis, the deletion sequences result in missing amino acids altering the bioactivity of the peptide, impacting the overall effectiveness or safety of the peptide-based therapeutic.

blank

Modification Sequences

Impurities might occur from unintended side reactions, modifying the original sequence. These sequence modifications can affect the therapeutic peptide's stability, binding ability, and pharmacokinetic properties.

blank

Incomplete Deprotection Sequences

Incomplete deprotection sequences result in residual protecting groups on the peptide, which can interfere with its intended biological activity and reduce pharmaceutical efficiency.

blank

Racemization

Racemization can cause chiral inversion of amino acids, altering the peptide configuration. This may affect the binding configurations, reducing the therapeutic efficacy, and even lead to undesired side effects.

blank

Purification Methods or SPPS

Inaccuracies in purification processes or SPPS can lead to the presence of by-products and unreacted reagents, compromising the purity and potency of the final therapeutic peptide.
