CYP51-IN-2 (compound 1i), a Fluconazole (HY-B0101) analog, is a potent antifungal agent. CYP51-IN-2 shows MIC₈₀ of 62.5 for Microsporum gypseum and Candida albicans.

Thiosemicarbazide is a vitamin B6 antagonist with anti-acne activity. Thiosemicarbazide is also a well-known source in the synthesis of heterocycles, and its derivatives have potential anticancer activity. Thiosemicarbazide (TSC: HL1) reacts with metal salts, urea (U), to prepare Co(II) and Cu(I) metal complexes. Thiosemicarbazide is also used in the fields of media communications and optical storage, and in the spectrophotometric detection of metals.

Antibacterial agent 282 has significant antibacterial activity against gram-positive bacterium and gram-negative bacterium with MICs of 0.1-1.56 and 0.1-3.13 μg/mL, respectively (MBCs of 0.2-1.56 and 0.39-12.5 μg/mL). Antibacterial agent 282 potently disrupts and prevents biofilms formation of P. aeruginosa. Antibacterial agent 282 shows significant inhibitory activity towards the DNA gyrase from E. coli.

TLN-58 is an antimicrobial peptide. TLN-58 has antibacterial activity against S. aureus, S. epidermidis, and group A Streptococcus. TLN-58 also induces inflammatory cytokine mRNAs upregulation in normal human keratinocytes and NCL-SG3 cells.

Tuberactinomycin A is a basic cyclic peptide antibiotic and a group I intron RNA splicing inhibitor, with an IC₅₀ of 10 μM against the G-binding site of bacteriophage T4 group I intron RNA. Tuberactinomycin A exerts antibacterial effects by acting on the initiation and elongation steps of bacterial bacteria ribosomes to inhibit prokaryotic protein synthesis. Tuberactinomycin A competes with guanosine cofactors for binding to the G-binding site of group I intron RNA, forms electrostatic interactions with the RNA backbone, and inhibits the self-splicing of bacteriophage T4 td and sunY group I introns, and its inhibitory activity depends on Mg²⁺ concentration. Tuberactinomycin A can be used in studies related to bacterial infections.

Ampicillin (sodium) (Standard) is the analytical standard of Ampicillin (sodium). This product is intended for research and analytical applications. Ampicillin sodium (D-(-)-α-Aminobenzylpenicillin sodium salt) is a broad-spectrum beta-lactam antibiotic against a variety of gram-positive and gram-negative bacteria.

Gemifloxacin mesylate (SB-265805S; LB-20304a) is an orally active broad-spectrum quinolone antibacterial antibiotic. Gemifloxacin mesylate inhibits DNA synthesis by inhibiting DNA gyrase and Topoisomerase IV activities. Gemifloxacin mesylate has potent antibacterial activities against gram-positive bacteria in vitro efficacy study, particularly Streptococci and Staphylococci. Gemifloxacin mesylate has been used in the research of respiratory tract infections.

Antibiotic adjuvant 4 (Compound 13) is an Antibiotic adjuvant and efflux pump inhibitor. Antibiotic adjuvant 4 exhibits potent efflux pump inhibitory activity. Antibiotic adjuvant 4 significantly downregulates virulence-related genes of Staphylococcus aureus when used alone or in combination with antibiotics. Antibiotic adjuvant 4 enhances the efficacy of Ciprofloxacin (HY-B0356) against multiagent-resistant Staphylococcus aureus strains.

Betamethasone succinate (NSSL-BMS) is a nano-formulation that can cross the blood-brain barrier. Betamethasone succinate is prepared by encapsulating the Betamethasone (HY-13570) semi-succinate in PEG-liposomes. Betamethasone succinate utilizes the enhanced permeation and retention effects of liposomes to target and deliver the potent glucocorticoid to the inflammatory sites. Betamethasone succinate inhibits the secretion of pro-inflammatory cytokines (such as TNF-α and IL-6) while maintaining the level of anti-inflammatory cytokine TGF-β. Betamethasone succinate can be used in the research of arthritis and cerebral malaria.
