Abstract
Aim: In this study, novel hybrid structures of pyrimido-indole-oxadiazole were developed as MDM2 inhibitors for restoring the regular function of the p53. Materials & methods: A multistep chemical pathway was used to synthesize the derivatives. Nutlin-3a was used as a standard lead in molecular docking and molecular dynamics simulations. Finally, cytotoxicity was evaluated against MCF-7 cancer cells versus Doxorubicin. Results: The most promising candidate was 12c, which had an NO2 group in the para position of the oxadiazole ring (IC50: 1.1 μM). A satisfactory result was obtained with the combined application of 12c and Doxorubicin (IC50 decreased to 0.63 μM), which could be potentially attributed to MDM2 inhibition. Conclusion: These hybrid structures can be further investigated as potential MDM2 inhibitors.

[DOI: 10.2174/1570179417666200417112106] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 01/30/2020] [Accepted: 03/12/2020] [Indexed: 12/17/2022]
Abstract
Background:
Urea, thiourea, and 1,2,4-oxadiazole compounds are of great interest due to their
different activities such as anti-inflammatory, antiviral, analgesic, fungicidal, herbicidal, diuretic,
antihelminthic and antitumor along with antimicrobial activities.
Objective:
In this work, we provide a new series of potential biologically active compounds containing both
1,2,4-oxadiazole and urea/thiouprea moiety.
Materials and Methods:
Firstly, 5-chloromethyl-3-aryl-1,2,4-oxadiazoles (3a-j) were synthesized from the
reaction of different substituted amidoximes (2a-j) and chloroacetyl chloride in the presence of pyridine by
conventional and microwave-assisted methods. In the conventional method, 1,2,4-oxadiazoles were obtained in
two steps. O-acylamidoximes obtained in the first step at room temperature were heated in toluene for an average
of one hour to obtain 1,2,4-oxadiazoles. The yields varied from 70 to 96 %. 1,2,4-oxadiazoles were obtained under
microwave irradiation in a single step in a 90-98 % yield at 160 °C in five minutes. 5-aminomethyl-3-aryl-1,2,4-
oxadiazoles (5a-j) were obtained by Gabriel amine synthesis in two steps from corresponding 5-chloromethyl-3-
aryl-1,2,4-oxadiazoles. Finally, twenty new urea (6a-j) and thiourea (7a-j) compounds bearing oxadiazole ring
were synthesized by reacting 5-aminomethyl-3-aryl-1,2,4-oxadiazoles with phenyl isocyanate and isothiocyanate
in tetrahydrofuran (THF) at room temperature with average yields (40-70%).
Results and Discussions:
An efficient and rapid method for the synthesis of 1,2,4-oxadiazoles from the
reaction of amidoximes and acyl halides without using any coupling reagent under microwave irradiation has
been developed, and twenty new urea/thiourea compounds bearing 1,2,4-oxadiazole ring have been synthesized
and characterized.
Conclusion:
We have synthesized a new series of urea/thiourea derivatives bearing 1,2,4-oxadiazole ring. Also
facile synthesis of 3,5-disubstituted 1,2,4-oxadiazoles from amidoximes and acyl chlorides under microwave
irradiation was reported. The compounds were characterized using FTIR, 1H NMR, 13C NMR, and elemental
analysis techniques.

Abstract
Five-membered 1,2,4-oxadiazole heterocyclic ring has received considerable attentionbecause of its unique bioisosteric properties and an unusually wide spectrum of biological activities.Thus, it is a perfect framework for the novel drug development. After a century since the1,2,4-oxadiazole have been discovered, the uncommon potential attracted medicinal chemists'attention, leading to the discovery of a few presently accessible drugs containing 1,2,4-oxadiazoleunit. It is worth noting that the interest in a 1,2,4-oxadiazoles' biological application has been doubledin the last fifteen years. Herein, after a concise historical introduction, we present a comprehensiveoverview of the recent achievements in the synthesis of 1,2,4-oxadiazole-based compounds and themajor advances in their biological applications in the period of the last five years as well as briefremarks on prospects for further development.
