Elsayed SA, Saad EA, Mostafa SI. Development of New Potential Anticancer Metal Complexes Derived from 2-Hydrazinobenzothiazole. Mini Rev Med Chem 2019; 19:913-922. [DOI: 10.2174/1389557518666181017143548] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2018] [Revised: 10/01/2018] [Accepted: 10/14/2018] [Indexed: 12/19/2022]
Abstract
Background:
Due to the side effects of clinically approved anticancer drugs there is a great
need to explore and develop new metal-based anticancer drug molecules of high efficiency with less or
no side effects.
Objective:
To synthesize new metal complexes of 2-hydrazinobenzothiazole (hbt) and to investigate
their potential anticancer characteristics.
Methods:
New five complexes; [VO(hbt)2SO4].4H2O (1), [Ru(hbt)2Cl3(H2O)] (2), [M(hbt)2Cl2] [M(II) =
Pd (3), Pt (4)] and [Ag(hbt)2].NO3 (5) were prepared and their structure was investigated by means of FTIR,
1H NMR, ESI-MS and UV-Vis spectra, elemental and thermal analysis, magnetic and molar conductance
measurements. The ligand and its complexes were examined as anticancer agents against Ehrlich
ascites carcinoma (EAC) and human cancer cells (hepatocellular carcinoma Hep-G2, mammary gland
breast cancer MCF-7 and colorectal carcinoma HCT-116). This feature is further supported by the DNAmetal
complexes binding ability. In addition, anti-oxidation activity of the complexes was investigated.
Results:
Complex (5) shows the highest anticancer activity with IC50 of 5.15, 9.9, 13.1 and 17.7 µg/mL
for EAC, HePG-2, MCF-7 and HCT-116, respectively. Complexes (2) and (3) show promising cytotoxicity
against EAC and HePG-2 cells with IC50 5.49 and 16.2 µg/mL, respectively. While, complexes
(1) and (4) show optimistic cytotoxicity against EAC with IC50 of 9.63 and 11.25 µg/mL, respectively.
The order of DNA binding ability of the complexes is (5) > (3) > (2) > (1) > (4). Among the five complexes,
complex (5) shows the best anti-oxidation activity.
Conclusion:
Complex (5) showed the highest DNA binding ability, anti-oxidation and anticancer activities.

Abstract
In the present work we are reporting the synthesis and binding interaction of a saturated fatty acid containing 9-aminoacridine derivative (AC-PA) with ct-DNA and β-cyclodextrin (β-CD). From Steady-state fluorescence experiments this newly synthesized 9-aminoacridine derivative, AC-PA, shows more efficient binding interaction with ct-DNA as compared to the 9-aminoacridine (AC). The extent of interaction of AC-PA and AC with ct-DNA was found out by calculating the fluorescence quenching by using Stern-Volmer quenching equation. The calculated quenching constants of AC-PA and AC are (4.5 ± 0.5) × 103M-1 (3.7 ± 0.5) × 103M-1 respectively. The mechanism of fluorescence quenching of AC-PA and AC, were understand by using Stern-Volmer plots as well as time-resolved fluorescence experiments. The fluorescence quenching of AC-PA and AC by ct-DNA are static in nature and take place by formation of ground state complexes. The binding mode between AC-PA and AC were understood by DNA melting analysis experiment. The DNA melting analysis experiments were reveals that the binding interactions between fluorophores (AC-PA and AC) with ct-DNA are intercalative in nature. The melting temperature and mode of binding intercalative mode of binding between AC-PA and AC were further confirmed by DSC and CD experiments. The steady-state and time-resolved fluorescence parameters of AC-PA are quite sensitive towards the formation of inclusion complexes between AC-PA and β-CD. Long hydrophobic tail containing acridine conjugate (AC-PA) shows more efficient binding interactions with the β-CD and the calculated binding constants value of AC-PA is 0.51 × 102M-1. Whereas, the parent molecule, AC not showing any binding interactions with β-CD.

Abstract
Natural d-DNA and l-DNA are mirror-image counterparts. However, because of the inherent flexibility and conformation diversity of DNA, it is still not clear how enantiomeric compounds recognize d-DNA and l-DNA. Herein, taking G-quadruplex (G4) DNA as an example that has diverse conformations and distinct biofunctions, the binding of ten pairs of iron triplex metallohelices to d- and l-G4 DNA were evaluated. The Δ-enantiomer binds to d-DNA and the Λ-enantiomer binds to l-DNA, exhibiting almost the same stabilization effect and binding affinity. The binding affinity of the Δ-metallohelix with d-G4 is nearly 70-fold higher than that of Λ-metallohelix binding d-G4. Δ-Metallohelix binding to d-G4 follows a two-step binding process driven by a favorable enthalpy contribution to compensate for the associated unfavorable entropy.

Abstract
In the course of developing ultrasensitive and quantitative electrochemical point-of-care analytical tools for genetic detection of infectious diseases, osmium(ii) metallointercalators were revealed to be suitable and efficient redox probes to monitor the in vitro DNA amplification [Defever etal, Anal. Chem., 2011, 83, 1815-1821]. In this work, we thus propose a complete computational protocol in order to evaluate the affinity between Os(ii) complexes with double-stranded DNA. This protocol is based on molecular dynamics, with the parametrization of the GAFF force field for the Os(ii) complexes presenting an octahedral environment with polypyridine ligands, and QM/QM' calculations to evaluate the binding energy. For three Os(ii) probes and different binding sites, molecular dynamics simulations and interaction energies calculated at the QM/QM' level are successively discussed and compared to experimental data in order to identify the most stable binding sites. The computational protocol we propose should then be used to design more efficient Os(ii) metallointercalators.

Fast and accurate fitting and filtering of noisy exponentials in Legendre space. PLoS One 2014; 9:e90500.

Abstract
The parameters of experimentally obtained exponentials are usually found by least-squares fitting methods. Essentially, this is done by minimizing the mean squares sum of the differences between the data, most often a function of time, and a parameter-defined model function. Here we delineate a novel method where the noisy data are represented and analyzed in the space of Legendre polynomials. This is advantageous in several respects. First, parameter retrieval in the Legendre domain is typically two orders of magnitude faster than direct fitting in the time domain. Second, data fitting in a low-dimensional Legendre space yields estimates for amplitudes and time constants which are, on the average, more precise compared to least-squares-fitting with equal weights in the time domain. Third, the Legendre analysis of two exponentials gives satisfactory estimates in parameter ranges where least-squares-fitting in the time domain typically fails. Finally, filtering exponentials in the domain of Legendre polynomials leads to marked noise removal without the phase shift characteristic for conventional lowpass filters.
