fibrogenesis

Cilostazol (OPC 21) is a Phosphodiesterase 3 Inhibitor. The mechanism of action of cilostazol is as a Phosphodiesterase 3 Inhibitor.

SDKPDMAEIEKFDKSK acetate is a thymosin β4 derivative. Thymosin β4 inhibits PDGF-BB-induced fibrogenesis, proliferation and migration of HSC by blocking Akt phosphorylation.

safironil is a novel antifibrotic compound and a competitive inhibitor of collagen synthesis. safironil inhibited in vitro experiments on fibroblast activation monitored by collagen I mRNA or smooth muscle alpha-actin levels, and fibrogenesis as judged by type I and type III collagen and laminin production. safironil had no effect on the size of liver granulomas without altering total hydroxyproline, but altered the pattern of fibrosis by increasing type III and decreasing type I collagen deposition.

GP 1a is a potent agonist of cannabinoid receptor 2 (CB2) (EC50=7.1), as shown in cAMP, GTPγS and β-arrestin recruitment assays. GP 1a is approximately 30-fold more selective for CB2 receptors than CB1 receptors and increases P-ERK1/2 expression in HL-60 cells in vitro. GP 1a is beneficial for skin wound healing. GP 1a inhibits inflammation and fibrogenesis while promoting epithelial re-formation.

1. Peimisine (Ebeiensine) can affect M-receptor, excit β-receptor, restrain the release of internal calcium, and promote to releaseing nitrogen monoxidum in order to relax tracheal smooth muscle and relieve asthma. 2. Peimisine can attenuate lung tissue injury( ALI), LDH and MDA amount in ALI mice in a dose dependent manner, it also lower the total protein, total white blood cells, lymphocyte and neutrophilic leukocyte in bronchoalveolar lavage fluid( BALF); suggests that peimisine can play a protective role against LPS-induced acute lung injury. 3. Peimisine has the protective effect on the experimental hepatic fibrosis formation, the possible mechanisms are associated with inhibiting fibrogenesis and fibrosis accumulation, and decreasing lipid peroxidation. 4. Peimisine can inhibit angiotensin I converting enzyme activity in a dose-dependent manner, displaying 5 % inhibitory concentration values of 526.5 microM, thus, it may have antihypertensive action.

SC-236 (Sc 236) is an orally active and selective inhibitor of COX-2 (IC50 of 0.005 μM and 17.8 μM for COX-2 and COX-1, respectively).

L002, a potent, cell-permeable, reversible, and specific acetyltransferase p300 (KAT3B) inhibitor with an IC50 of 1.98 μM, directly binds the acetyl-CoA pocket and competitively inhibits the FATp300 catalytic domain. By blocking histone acetylation, p53 acetylation, and STAT3 activation, L002 shows potential in the treatment of hypertension‐induced cardiac hypertrophy and fibrogenesis.

Methacycline hydrochloride (Rondomycin) is a broad-spectrum semisynthetic antibiotic related to TETRACYCLINE but excreted more slowly and maintaining effective blood levels for a more extended period.

SDKPDMAEIEKFDKSK is a peptide derived from thymosin β4 (Tβ4).
