Retro-2 (2-{[(5-methyl-2-thienyl)methylene]amino}) is a plant toxin ricin inhibitor, itprotects HeLa cells against Ricin, Stx1 and Stx2, selectively blocks retrograde toxin trafficking at the early endosome-TGN (trans-Golgi network) interface.

CDKI-73 is a potent CDK9 inhibitor (Ki: 4 nM). It shows selective toxicity to CLL cells(LD50=80 nM) versus normal B cell and normal CD34+ cell(LD50>20 uM).The inhibition of CDK9 induces apoptosis and potentiates the effect of cisplatin.

Human α-defensin 5 is an antiviral peptide that inhibits the infection of non-enveloped viruses such as AdV, HPV, and polyomaviruses, with an IC50 range of 0.6-1.25 μM specifically for HPV16. It functions by binding to the viral capsid and preventing viral escape from the endosome. Additionally, Human α-defensin 5 enhances HIV attachment to the cell surface and exhibits parasiticidal activity [1].

LAH4 acetate is the α-helical structure of the designed amphoteric peptide antibiotic, which is capable of complexing DNA, associating with the cell surface membrane and wrapped in the endosome, which is destroyed with the decrease of pH value. It has strong antibacterial, nucleic acid transfection and cell penetration activities. LAH4 acetate has high plasmid DNA transmission capacity. LAH4 acetate has a strong affinity for anions in bacterial membranes.
