The application covers the following chemical substances approved under the simplified registration pathway: 1. (4S)-5-[[(1S)-3-amino-1-[[(1S)-2-[(2-amino-2-oxoethyl)methylamino]-2-oxo-1-(3-pyridinemethyl)ethyl]carbamatel]-3-oxopropyl]amino]-4-[[(2S)-2-(9-H-fluorene-9-ylmethoxycarbonylamino)-3-(2-naphthyl)propionyl]amino]tetrahydropyran-4-carbonyl]amino]-5-oxovalerate tert-butyl 2. (4S)-5-[[(1S)-3-amino-1-[[(1S)-2-[(2-amino-2-oxoethyl)methylamino]-2-oxo-1-(3-pyridinemethyl)ethyl]carbamatel]-3-oxopropyl]amino]-4-[[(2S)-2-(9-H-fluorene-9-ylmethoxycarbonylamino)-3-(2-naphthyl)propionyl]amino]tetrahydropyran-4-carbonyl]amino]-5-oxovalerate tert-butyl 3. 2-Acrylic (2,2-dimethyl-1,3-dioxentyclo-4-yl)methyl ester 4. 4,5-dihydro-5,5-diphenyl-1,2-oxazole-3-carboxylate 5. Reaction product of 2-methyl-2-acrylic substituted alkyl ester with 1,6-diisocyanate to hexane 6. Lithium zirconium phosphate 7. 4-fluoro-3-hydroxybenzoic acid 8. (2S)-2-[[(4 R,7 S,10 S,13 S,16 S,19R)-19-acetylamino-7-(4-acetylaminobutyl)-16-(2-amino-2-oxyethyl)-13-[(1R)-1-tert-butoxyethyl]-3,3,20,20-tetramethyl-10-[(7-methyl-1 H-indole-3-yl)methyl]-6,9,12,15,18-pentaoxo-1,2-dithio-5,8,11,14,17-pentazacycloeicosane-4-carbonyl]amino]-3-[4-[2-(tert-butoxycarbonylamino)ethoxy]phenyl]propionic acid 9. S1,S1',S1''-[(2,4,6-trioxo-1,3,5-triazine-1,3,5(2 H,4H,6 HHydrolysate of )-tri-3,1-propylene glycol]thioacetate 10. (5S)-3-(3,5-difluorophenyl)-5-[(1S)-1-hydroxyethyl]-4 H-isooxazole-5-carboxylateisopropyl ester The applications were found to meet regulatory requirements and are proposed for approval under China's environmental management framework for new chemical substances. The announcement is published for public consultation from April 3 to April 8, 2026, during which comments may be submitted through designated communication channels.
