Abstract

Veliparib (ABT-888) is a potential anti-cancer drug acting as a PARP inhibitor. It kills cancer cells by blocking a protein called PARP, thereby preventing the repair of DNA or genetic damage in cancer cells and possibly making them more susceptible to anticancer treatments. Veliparib (ABT-888) is being investigated to treat squamous and non-squamous non-small cell lung cancer, BRCA breast cancer, triple negative breast cancer and ovarian cancer.

Biological activity

Veliparib (ABT-888) is a potent inhibitor of PARP1 and PARP2 with Ki of 5.2 nM and 2.9 nM in cell-free assays, respectively. It is inactive to SIRT2. Phase 3.

In vitro

Veliparib (ABT-888) is a potential anti-cancer drug acting as a PARP inhibitor,which inhibits PARP1 and PARP2 with Ki of 5.2 nM and 2.9 nM in cell-free assays,respectively.ABT-888 reduces clonogenic survival and inhibits DNA repair in H460 cells. ABT-888 inhibits the PARP activity with EC50 of 2 nM in C41 cells.

In vivo

ABT-888 inhibits PARP in B16F10 and 9L xenograft models, thus enhancing the anticancer activity of temozolomide. The Combined with other cytotoxic agents, ABT-888 shows strong antitumor effect in MX-1 xenograft model. ABT-888 reduces intratumor PAR levels by more than 95% at a dose of 3 and 12.5 mg/kg according to the the size of tumors in A375 and Colo829 xenograft models.

Features

ABT-888 enhances the effectiveness of common cancer treatments, such as radiation therapy and alkylating agents.

Chemical Properties

Off-White Solid

Uses

ABT-888 is a potent, orally bioavailable PARP-1/-2 inhibitor shown to potentiate DNA damaging agents. The ability to potentiate temozolomide (TMZ) and develop a biological marker for PARP inhibition was evaluated in vivo.

Definition

ChEBI: A benzimidazole substituted with a carbamoyl group at C-4 and a (2R)-2-methylpyrrolidin-2-yl moiety at C-2. It is a potent, orally bioavailable PARP inhibitor.

Biological Activity

abt-888, also named as veliparib, is poly (adp-ribose) polymerase (parp) inhibitor and has demonstrated excellent in vivo efficacy in a broad spectrum of preclinical tumor models in combination with a variety of cytotoxic agents. parp is involved in dna repair and elevated parp levels can result in resistance to cytotoxic chemotherapy and radiation. so, parp inhibitors hold promise as chemotherapy and radiation sensitizers. abt-888 is also active on microsatellite instability (msi) cell lines harboring mutations in both mre11 and rad50 genes compared to microsatellite stable (mss) cell lines (wild-type for both genes).shivaani kummar, robert kinders, martin e. gutierrez, larry rubinstein, ralph e. parchment, lawrence r. phillips, jiuping ji, anne monks, jennifer a. low, alice chen, anthony j. murgo, jerry collins, seth m. steinberg, helen eliopoulos, vincent l. giranda, gary gordon, lee helman, robert wiltrout, joseph e. tomaszewski and james h. doroshow. phase 0

Check Digit Verification of cas no

The CAS Registry Mumber 912444-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,2,4,4 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 912444-00:
(8*9)+(7*1)+(6*2)+(5*4)+(4*4)+(3*4)+(2*0)+(1*0)=139
139 % 10 = 9
So 912444-00-9 is a valid CAS Registry Number.

Preparation method of veliparib

-

, (2020/08/12)

The invention discloses a preparation method of veliparib, which comprises the following steps: by using readily available L-alanine ethyl ester as a raw material, carrying out imidization, cyclization reduction and hydrolysis reaction to obtain a key chiral intermediate that is (R)-2-methylpyrrolidine-2-carboxylic acid, and carrying out one-step condensation on the intermediate to obtain the target compound veliparib. The method has the characteristics of easily available raw materials, mild conditions, simple process, safety, environmental protection and the like, and is suitable for industrial production.
