Biological Activity

Description

Carboplatin, a derivative of CDDP, is a DNA synthesis inhibitor which binds to DNA, inhibits replication and transcription and induces cell death and interfers with the cell's repair mechanism in A2780, SKOV-3, IGROV-1, and HX62 cells. It induces the formation of DNA interstrand crosslinks and DNA-protein crosslinks. Solutions are unstable and should be fresh-prepared.DMSO is not recommended to dissolve platinum-based drugs, which can easily lead to drug inactivation.

Targets

DNA synthesis ^[1]
(A2780, SKOV-3, IGROV-1, HX62 cells)

In vitro

Carboplatin exhibits an inhibitory effect on cell proliferation in a human ovarian cancer cell line panel, including A2780, SKOV3, and IGROV-1 cells with IC50 of 6.1 μM, 12.4 μM and 2.2 μM, respectively. ^[1] Carboplatin also show the anti-proliferative activities in lung carcinoid cell line, such as UMC-11, H727, and H835 cells with IC50 of 36.4 μM, 3.4 μM and 35.8 μM, respectively. ^[2]

In vivo

In A2780 tumor xenografts, Carboplatin (60 mg/kg via i.p.) given as single agents shows a modest antitumor effect with the relative tumor volumes on day 6 of 8.4 compared to the control of 11.9, and the day 6 tumor weights relative to control (T/C) of 67%. ^[1] For the VC8 (Brca2-deficient) xenografts, Carboplatin treatment delays tumor growth and reduces tumor mass by 42% compared to the vehicle group. ^[3]

Features

This product is not recommended to be dissolved in dimethylsulfoxide (DMSO).^[6]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines A2780, SKOV3, IGROV-1 and HX62 Concentrations 0-200 μM Incubation Time 72 hours Method 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assays: Exponentially growing A2780, SKOV3, IGROV-1 and HX62 ovarian cancer cells are plated in 96 well plates. A range of drug concentrations are added and the plates are incubated for 72 hours to allow for 3–4 doubling times. Each experiment is carried out in triplicate. Sulforhodamine B (SRB) assays: Exponentially growing A2780 cells are plated in 96 well microtitre plates. For experiments studying concomitant exposure, cells are exposed to increasing concentrations of both drugs for 96 hours. For experiments studying the effect of sequence of exposure to 17-AAG or carboplatin cells are exposed to increasing concentrations of 17-AAG or carboplatin for 24 hours. A period of 24-hour exposure to the first agent is chosen so that the A2780 cells would be exposed to the first drug for at least one doubling time (18-24 hours). The cells are then washed with sterile phosphate buffered saline and the medium is replenished. Following this, the second drug (to which the cells are not exposed to in the first 24 hours) or medium is added for 96 hours. All experiments are carried out in triplicate. The results of combination studies are analyzed using the well-established principles of median effect analysis method. The effects of the combination are calculated using an in-house spreadsheet.
Animal Study:^{^[1]}	Animal Models The A2780 human ovarian cancer cell line is grown as a subcutaneous xenograft in female athymic NCr nude mice (nu/nu) in each flank. Dosages ≤60 mg/kg (When Carboplatin is dissolved in sodium chloride solution, it will induce physio-chemical and pharmacokinetic changes.) Administration Administered via i.p.
