Clinical stage generative artificial intelligence (AI)-driven biotechnology company InSilico Medicine (“InSilico”), today announced that the Journal of Medicinal Chemistry, an ACS Publications journal focusing on critical studies about molecular structure and biological activity, has published the company’s discovery of a novel PHD inhibitor for the treatment of anemia. The academic breakthrough is powered by Chemistry42, its proprietary generative chemistry platform consisting of more than 40 selected generative models.
As suggested in previous studies, the inhibition of prolyl hydroxylase domain enzymes (PHD) influences fundamental biological processes, including red blood cell production by regulating the Nobel prize-winning HIF-α pathway, thus indicating potential for the treatment of CKD-induced anemia.
Guided by a structure-based drug discovery (SBDD) strategy, Insilico’s scientists gathered structure information on the PHD target and known molecules, and generated series of molecule candidates with the help of Chemistry42. Utilizing built-in filters covering drug-likeness, pharmacophore clues, synthesis evaluation and more, the AI-generated candidates were ranked and prioritized before a hit compound was produced for further optimization.
“Thanks to Chemistry42, we had end-to-end assistance from molecule generation to hit compound selection,” said Xiaoyu Ding, the computational chemist sharing first authorship. “With the power of generative artificial intelligence, we could accelerate the drug discovery process without compromises in novelty or quality.”
Afterward, several rounds of synthesis test optimization yielded lead compound 15, which demonstrated a favorable in vitro/in vivo ADMET profile, a clean safety profile, and promising PK properties in multiple species. Moreover, the compound was proven to alleviate anemia in a rat disease model, with relatively simple synthesis steps.
“Given that more than 10% of the global population suffers from CKD, Insilico’s novel molecule could be a meaningful for further investigations and patients worldwide,” said Jianyu Xu, the medicinal chemist who co-authored the paper. “After comprehensive research into PHD inhibitors already available on the market, we hope to develop a novel noncarboxylic acid molecule for better permeability and PK profiles.”

A groundbreaking study conducted by Professor Jiyoung Park and her research team in the Department of Biological Sciences at UNIST has identified FAM3C, a metabolism-regulating signaling molecule produced by cancer-associated adipocytes (CAAs), as a key regulator of breast cancer progression within the tumor microenvironment (TME). The findings, published in the prestigious academic journal Cancer Research, shed light on the potential for targeted therapies in the treatment of breast cancer.
The study demonstrates that overexpression of FAM3C in cultured adipocytes significantly reduces cell death in both adipocytes and co-cultured breast cancer ...

There are approximately 425 million people worldwide with diabetes. Approximately 75 million of these inject themselves with insulin daily. Now they may soon have a new alternative to syringes or insulin pumps. Scientists have found a new way to supply the body with smart insulin.
The new insulin can be eaten by taking a capsule or even better, within a piece chocolate.
Inside these we find tiny nano-carriers to which the insulin is encapsulated. The particles are 1/10,000th the width of a human hair and so small that you cannot even see them under a normal microscope.
“This ...

MIAMI, FL – January 19, 2024 – Researchers from Miami Cancer Institute, part of Baptist Health South Florida, today published a study in Trends in Cancer that analyzes the use of tissue-agnostic therapeutics in patients with primary brain tumors (PBTs). The publication describes the current and potential impact of tissue-agnostic therapies on the management of PBTs. As part of the publication, the researchers discuss data from clinical trials of tissue-agnostic targets for PBTs in the context of challenges in managing these tumors. They also describe additional tissue-agnostic ...

A McGill-led team of researchers have made an important discovery shedding light on the genetic basis of a rare skeletal disorder. The study, published in Nature Communications, reveals that a defect in a specific gene (heterozygous variants in the matrix Gla protein, or MGP) may cause a disorder that affects the structure of connective tissues that supports the body.
MGP is a special protein found in blood vessels and cartilage that helps prevent the hardening of these tissues in the body. If MGP is completely missing, it can lead to Keutel syndrome, a rare condition where tissues become calcified, causing issues in the skeleton and blood vessels.
However, in this case, ...

Infantile epileptic spasms syndrome (IESS), often called infantile spasms, is the most common form of epilepsy seen during infancy. Prompt diagnosis and referral to a neurologist are essential. But research suggests infants are likely to experience delays in referral to a neurologist if their families are from historically marginalized racial/ethnic backgrounds. A new open-access training module for front-line providers from OPENPediatrics, an online learning community launched by Boston Children’s Hospital, aims to change that.
The free, publicly accessible Infantile Spasms curriculum includes short lectures and videos illustrating ...

In studying social mobility in today’s industrialized nations, researchers typically rely on data from the World Economic Forum or, in the United States, the General Social Survey. But examining the same phenomena from past centuries is a more daunting task because relevant statistics are harder to come by.
However, a social science research team has now discovered a way to examine professional advancement in medieval China (618-907 CE) by drawing from the tomb epitaphs during the Tang Dynasty. These epitaphs contain the ancestral lineages, names, and office titles (e.g., Minister of Personnel, Minister of the Court of Judicial Review, and ...

BUFFALO, N.Y. – Think of a time when you had two different but similar experiences in a short period. Maybe you attended two holiday parties in the same week or gave two presentations at work. Shortly afterward, you may find yourself confusing the two, but as time goes on that confusion recedes and you are better able to differentiate between these different experiences.
New research published in Nature Neuroscience published on January 19, reveals that this process occurs on a cellular level, findings that are critical to ...
