Ajoene is a disulfide that has been found inA. sativumand has diverse biological activities, including antibacterial, anticancer, antiplatelet, and antioxidant properties.1,2,3,4It is active against Gram-positive (MICs = 5-160 µg/ml) and Gram-negative bacteria (MICs = 136-200 µg/ml), as well as yeasts (MICs = 10-20 µg/ml).1Ajoene is cytotoxic to mouse melanoma cells (IC50= 18 µM), as well as human colon, lung, mammary, and pancreatic cancer cells (IC50s = 7-41 µM).2It reduces tumor growth in a B16/BL6 mouse model of melanoma when administered at a dose of 25 mg/kg every other day and decreases the number of lung metastases when administered prior to tumor cell inoculation at doses ranging from 1-25 mg/kg. It inhibits ADP- or collagen-induced platelet aggregation in isolated baboon platelets when used at concentrations ranging from 75 to 150 µg/ml and in platelet-rich plasma isolated from baboons when administered at a dose of 25 mg/kg.3Ajoene (25 mg/kg) prevents thrombus formation on damaged arterial walls in heparinized pigs in anin situmodel of thrombogenesis.5It also reduces high-fat diet-induced hepatic steatosis, histopathological markers of liver damage, thiobarbituric acid reactive substances (TBARS) formation, and protein oxidation in a mouse model of non-alcoholic fatty liver disease (NAFLD).4 1.Naganawa, R., Iwata, N., Ishikawa, K., et al.Inhibition of microbial growth by ajoene, a sulfur-containing compound derived from garlicAppl.

6(5H)-Phenanthridinone is an inhibitor of poly(ADP-ribose) polymerase 1 (PARP1) and PARP2. It decreases radiation-induced PARP activity and proliferation of RDM4 murine lymphoma cells. 6(5H)-Phenanthridinone reduces NF-κB-induced transcription of the genes encoding TNF-α, IL-2, and IFN-γ in rat lymphocytes. In vivo, 6(5H)-phenanthridinone reduces spinal cord expression of inducible nitric oxide synthase (iNOS), IL-1β, TNF-α, IL-2, and IFN-γ and reduces disease score in a rat model of experimental autoimmune encephalomyelitis (EAE). It also decreases serum levels of lactate dehydrogenase as well as hepatic lipid peroxidation, oxidative DNA damage, and PARP levels.

H-Leu-Ser-Lys-Leu-OH (LSYL), a latency-associated peptide located at the amino terminus of LAP, inhibits TGF-β1 activation by binding with KRFK, thereby obstructing TGF-β1 signal transduction and inhibiting the progression of hepatic damage and fibrosis [1].

Fulvotomentoside B, a saponin derived from Lactobacillus flavus, displays hepatoprotective properties. It notably decreases serum glutamate pyruvate transaminase (SGPT) and triacylglycerol (GT) concentrations in mice subjected to hepatic injury induced by CCl₄, d-galactosamine (d-gal), and acetaminophen, while also significantly mitigating liver tissue damage [1].

Tat-Gap 19, a peptide inhibitor of connexin43 (Cx43) hemichannels, is derived from the HIV-1 Tat protein transduction domain fused with a nine-amino acid sequence from Cx43 residues 128-136. This compound, at a concentration of 10 µM, effectively suppresses glutamate-induced ATP release in primary rat hepatocytes, indicating inhibition of Cx43 hemichannel activity. Furthermore, Tat-Gap 19 demonstrates therapeutic potential by significantly reducing infarct volume in a mouse cerebral ischemia-reperfusion injury model following middle cerebral artery occlusion (MCAO) at a dosage of 25 mg/kg. Moreover, its intraperitoneal administration at 1 mg/kg per day ameliorates fibrosis and decreases the area of hepatic stellate cells, the precursors to myofibroblasts, expressing α-smooth muscle actin (α-SMA), in a model of thioacetamide-induced liver damage. Additionally, it enhances superoxide dismutase (SOD) activity in hepatic cells from the treated mice, indicating its antioxidative benefits.
