Metabolites found in humans are also observed in monkeys, and all metabolites were found to possess <10% of the activity of the parent drug. of the administered radiolabel in the human ADME study.
Metabolism of 2022 FDA approved smallmoleculedrugs part 2 Mixing it Up By Julia Shanu-Wilson In Part 1 of this topic we looked at metabolism of the smallmoleculedrugs approved by the FDA in 2022 that were mediated by CYP3A4.
Metabolism of 2023 FDA Approved SmallMolecules – PART 1 By Julia Shanu-Wilson 2023 was a fruitful year for drug approvals by the FDA, with a crop of 34 smallmolecules out of a total of 55 new drugs [1]. Enzymes involved include CYP1A2, CYP2C8, CYP3A4, CYP4F2, and aldehyde oxidase (AOX).
G protein-coupled receptors (GPCRs) represent a cornerstone of modern drug discovery due to their crucial role in regulating human physiology and their involvement in numerous diseases. In the early days, each GPCR target required its own structure-modulating ConfoBody to be identified before starting any drug discovery.
Antibody-drug conjugates (ADCs) have been a groundbreaking approach to cancer treatment with their ability to deliver cytotoxic drugs directly to diseased cells while sparing healthy tissues. 1 However, efforts proved less effective than the original drugs, owing mostly to insufficient toxicity against cancer cells.
Dian Su’s journey from chemistry and proteomics to the DMPK of drug conjugates Following a different path comes naturally to Dian Su, Senior Director of DMPK at Bicycle Therapeutics. In her smallmolecule DMPK research, proteomics also served to identify reactive metabolites (e.g., Proteomics!
Finding smallmoleculedrugs is much harder than finding a needle in a haystack – discovering the right arrangement of atoms to bind precisely to a protein target to elicit a particular response is a problem of vast dimensionality. Yet the situation with smallmolecules is even worse.
While these approaches often produce encouraging initial results, the development of drug resistance remains a major obstacle for long-term patient survival. Classically, rational drug combinations are designed to target two nodes in the same oncogenic signalling pathway.
Picking up where we left off in Part I , this post covers several other ML in drug discovery topics that interested me in 2023. Most of the LLM activity in the drug discovery space in 2023 was reported as preprints from academic groups. Most of the drug discovery examples were underwhelming. Here’s the structure of Part II.
Data science has emerged as an innovative tool in the biopharmaceutical industry, leveraging the power of machine learning and artificial intelligence to drive innovation and efficiency across the entire drug development lifecycle.

The therapeutic dose of pirfenidone approved by the US Food and Drug Administration (FDA) for the treatment of IPF is 801 mg three times a day.
Is a novel target at the inflection point where enough evidence is available to suggest it may prove to be a compelling drug? and whether a molecule’s pharmacology can help to mitigate safety risk. In order to start building a case for or against a target, I like to start with genetics – first human and then mouse. in liver, in CNS)?
In this blog, we explain the role of clinical pharmacology in drug development and demonstrate how the right strategy can accelerate development under the US Food and Drug Administration (FDA) 505(b)(1) and 505(b)(2) New Drug Application (NDA) pathways.
This molecule shows immense potential as a pan-TEAD inhibitor, targeting advanced solid tumours. TEAD proteins are crucial for tumour progression and drug resistance, making them an attractive focus for therapeutic interventions. ISM6331 is a Pan-TEAD inhibitor with novel scaffold with good IP space, discovered by Chemistry42.
On July 31, 2024, the US Food and Drug Administration (FDA) announced Fiscal Year 2025 (FY2025) Prescription Drug User Fee Amendments of 2022 (PDUFA VII) fee rates for the review of human drug and biological product applications along with prescription drug program fees.
The 505(b)(2) new drug application (NDA) pathway offers a unique opportunity for smallmolecule developers to bring innovative products to market more efficiently by leveraging existing data they do not own or have right of reference to. Since there was no change in drug substance, the sponsor was able to reference the DMF.
Food and Drug Administration (FDA) clearance of an Investigational New Drug (IND) application for SLV213 for the treatment of COVID-19 and has dosed the first subjects in a Phase 1 clinical study. While SLV213 can be dosed orally or intravenously, Selva is first advancing it as an oral drug candidate for COVID-19. About SLV213.
This results in cleavage of the drug to two metabolites, M1 and M9, with only M1 retaining the 14C label. of total drug related material in plasma. Biotransformation studies which reveal significant cleavage of a drug could thus trigger a route involving dual radiolabelling. Eur J Drug Metab Pharmacokinet 48 , 411–425 (2023).
These assays provide insights into the molecular mechanisms of disease biology and drug response, enabling the characterisation of gene expression profiles and deviations in diseased cells. This platform can help identify and optimise pharmacologic properties of new drugs.
Food and Drug Administration (FDA) adopted an addendum to the guidance titled “ S1B(R1) Testing for Carcinogenicity of Pharmaceuticals ,” which had previously been finalized by the International Council for Harmonization (ICH). Pharmacokinetic and systemic exposure data is also important to consider. On November 1, 2022, the U.S.

Many drug makers are investing in new science and hope to develop new therapeutics that address autoimmune disease. Scientists will be testing a drug class targeting the C-reactive protein (CRP) marker of acute inflammation in the body. They’ll use software that searches available drugs, as well as drug-like compounds.
We commonly invoke the free drug hypothesis (FDH) in drug design which means that we assume that the free concentration at the site of action is the same as the free plasma concentration (the term ‘free drug theory’ is also commonly used although I prefer FDH).
