GS-441524-d is the deuterium labeled GS-441524 (HY-103586). GS-441524 is a potent, orally active and CNS-penetrant viral RNA-dependent RNA polymerase inhibitor. GS-441524 competes with natural nucleosides to block viral RNA transcription as an alternative substrate and RNA chain terminator. GS-441524 inhibits the replication of feline infectious peritonitis virus, African swine fever virus, and severe acute respiratory syndrome coronavirus 2. GS-441524 reduces viral RNA levels in cats. GS-441524 can be used in research related to feline infectious peritonitis, African swine fever, and coronavirus disease 2019 (COVID-19) .

Doxycycline (hydrochloride)	Apoptosis MMP Akt PI3K	Infection Neurological Disease Inflammation/Immunology Cancer
Doxycycline hydrochloride GMP is Doxycycline (hydrochloride) (HY-N0565A) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. Doxycycline hydrochloride is an orally active highly lipophilic, tissue-permeable MMP inhibitor with broad-spectrum antibacterial activity. Doxycycline hydrochloride is also a semi-synthetic antibiotic with chelating properties, which blocks bacterial protein synthesis and inhibits extracellular matrix degradation through interactions with zinc and calcium atoms. Doxycycline hydrochloride also inhibits mitochondrial biogenesis, translation, and the expression of respiratory chain proteins. Doxycycline hydrochloride induces apoptosis, inhibits autophagy and EMT, downregulates stem cell markers, and activates the PI3K-AKT pathway, thereby effectively inhibiting the viability and proliferation of cancer cells such as breast cancer cells. Doxycycline hydrochloride also promotes the survival and self-renewal of embryonic stem cells and neural stem cells, and reduces the frequency of medium changes in culture. Doxycycline hydrochloride has been applied in studies related to breast cancer, prostate cancer, bladder cancer, and other cancers .
