Description

AMY-101 (Cp40) is the efficient inhibitor of the central complement component C3, with sub-nanomolar affinity for C3 (KD=0.5nmol/L)[1]. AMY-101 is involved in regulating the immune response, regulating the complement system and the release of inflammatory mediators[2]. AMY-101 has been used in immune response research, anti-inflammatory experiments and antiviral study[3].

In vitro, AMY-101 treatment (20μmol/L) for 72 hours significantly reduced the production of pro-inflammatory mediators in human THP-1 cells[4]. Treatment of SV40-immortalized porcine aortic endothelial cells with AMY-101 at 20μg/ml for 1 hour almost completely inhibited the deposition of C3 fragments and C5b-9 on the cells[5].

In vivo, AMY-101 treatment (4mg/kg; 28 days) via subcutaneous injection daily to adult cynomolgus monkeys can significantly reduce the clinical indices measured for periodontal inflammation and tissue destruction[1]. In sensitized male rhesus monkeys, intramuscular injection of AMY-101 (2mg/kg/day; I.M.) for 16 days can inhibit lymphocyte activation and proliferation, prevent antibody-mediated rejection reactions, and prolong the survival period of kidney transplantation[6].

Protocol

Cell experiment [1]:

Cell lines

THP-1 cells

Preparation Method

THP-1 cells were seeded in 96-well plates at a density of 2.5 × 104cells per well with 200μL of complete RPMI 1640 medium that contained 50nmol/L Phorbol 12-Myristate 13-Acetate (PMA). The cells remained in incubation for 48 hours with an atmosphere of 5% CO2 at 37°C. The medium containing PMA was exchanged with complete RPMI(200μL/well) and cells rested for another 24 hours before treatment. The medium was switched to complete RPMI with 1%FBS two hours before treatment. The cells received a treatment with LPS at concentrations of 0.01 or 0.10μg/mL or Bitis arietans venom(BVA) at 5.0, 6.25, 12.5, 25.0, or 50.0μg/mL concentrations and saline as a negative control. After incubating the cells at 24, 48, and 72 hours the supernatants were collected and stored at −80°C for subsequent examination. The experimental cells received treatments with BVA at 50μg/mL concentration, AMY-101 at 20μmol/L concentration, and saline solution for periods of 24, 48, 72h. The MTT assay determined cell viability while the inflammatory cytokine kit measured cytokine levels.

Reaction Conditions

20μmol/L; 24, 48, 72h

Applications

AMY-101 significantly reduced the level of IL-1β for 72 hours and had an inhibitory effect on the activation of inflammasomes.
Animal experiment [2]:

Animal models

Adult cynomolgus monkeys

Preparation Method

The research utilized adult cynomolgus monkeys which ranged from 7 to 10 years old and weighed between 5.0 and 7.6 kilograms. After four weeks of program adaptation scientists used socially-placed monkeys in stainless steel cages for experiments. Research animals gain environmental richness from daily care by technicians and environment-rich items combined with visual contact with other animals. The research animals received specific quantities of authorized feed mixture as part of their diet. The animals had unrestricted access to fresh drinking water. Deliver AMY-101 subcutaneously at a rate of 4mg/kg/day for 28 days through a 1mL insulin-safe syringe fitted with a 28G×1/2-inch needle. Conduct clinical examinations initially at week 0 and then at each of the subsequent study intervals of weeks 1 through 4 and at week 11. Samples were collected from both gingiva and bone tissue at the beginning of the study and again at 4 and 11 weeks.

Dosage form

4mg/kg /day for 28 days; s.c.

Applications

AMY-101 treatment significantly reduced the inflammatory clinical parameters of naturally occurring chronic periodontitis in adult cynomolgus monkeys.
