5-HT2A&5-HT2C agonist-3 (compound 4e) is an orally bioavailable and blood-brain barrier penetrant agonist of 5-HT2A and 5-HT2C. 5-HT2A&5-HT2C agonist-3 increases intracellular calcium levels in cells overexpressing 5-HT2A or 5-HT2C receptors, and shows no activity against 5-HT2B receptors. 5-HT2A&5-HT2C agonist-3 can be used for the research of neuropsychiatric disorders.

5-Amino-2'-deoxyuridine is a thymidine analogue and substrate for chemical reaction. 5-Amino-2'-deoxyuridine can be use in the preparation of labeled probes for DNA microarray analysis.

4-Bromoisophthalic acid (4-Bromo-1,3-benzenedicarboxylic acid) is a metal-organic framework (MOF).

3'-O-(2-Nitrobenzyl)-dCTP is a reversible terminator. 3'-O-(2-Nitrobenzyl)-dCTP can be recognized and incorporated by polymerases, thereby temporarily terminating primer extension during DNA synthesis. After incorporation into the extending DNA strand, 3'-O-(2-Nitrobenzyl)-dCTP temporarily halts the DNA polymerase extension reaction, and its 3'-O-(2-nitrobenzyl) blocking group can be removed by laser irradiation to regenerate a free 3'-OH for subsequent primer extension cycles. 3'-O-(2-Nitrobenzyl)-dCTP is applicable for resolving homopolymeric regions in DNA templates.

3-Benzylmalic acid (3-Benzylmalate) can be converted from 2-Benzylmalic acid through a HphCD-mediated hydroxyl isomerization reaction.

3-[4-(2-Propyn-1-yloxy)phenyl]-2H-azirine (Compound AZ-9) is a reactive probe based on 3-phenyl-2H-azirine, enabling chemoselective bioconjugation of carboxyl residues in proteins with excellent labeling efficiency and specificity under both in vitro and in situ conditions in live cells.

2-Oxo-(4R)-hydroxy-5-aminovaleric acid is a nucleoside metabolite.

2'-Nitroflavone is a PARP1 inhibitor. 2'-Nitroflavone inhibits the proliferation, induces cell cycle arrest and apoptosis of triple-negative breast cancer cells. 2'-Nitroflavone also inhibits the migration of triple-negative breast cancer cells and endothelial cells. 2'-Nitroflavone exhibits antitumor activity and can be used in the research of tumors such as triple-negative breast cancer.

2-MSP(4-OMe)-5-HA-PEG8-VA-Exatecan is a Drug-linker conjugates for ADC consisting of the ADC Cytotoxin Exatecan and a linker. 2-MSP(4-OMe)-5-HA-PEG8-VA-Exatecan can be used for synthesis of ADCs.

23(Z),26(Z),29(Z),32(Z),35(Z)-Octatriacontapentaenoic acid is a fatty acid.

20-HETE IN-3 is an orally bioavailable 20-HETE synthesis inhibitor. 20-HETE IN-3 can be used in the research of obesity.

20b-Dihydroprogesterone (Compond III) is a C-21 steroid found in water beetles Cybister limbatus, C. tripunctatus and C. confuses.

20(Z),23(Z),26(Z),29(Z),32(Z),35(Z)-Octatriacontahexaenoic acid is an unsaturated fatty acid.
