Acyclic vicinal polyol complexes related to cisplatin were synthesized from D-mannitol by stereocontrolled manipulation of the hydroxy groups. Controlled cleavage of a 3,4-diazido hexitol gave the corresponding D-threitol and D-xylitol analogs, which were converted to their diamino platinum complexes. The antitumor activity of these compounds is reported.

Hydroxy Groups

A series of analogs of (R,R)-1,2-diaminocyclohexane dichloroplatinum(II) (DACH) containing stereochemically defined hydroxy groups and appropriate acidic leaving groups were synthesized and tested as antitumor agents. The (1α,2β,3α,4β)-1,4-dihydroxy-2,3-diaminocyclohexane analog showed the highest potency against P388 leukemia in mice. The results indicate that increasing the hydrophilicity of the platinum complex to a certain extent could improve the antitumor activity of the drug. It is also likely that the stereochemical disposition of the substituents on the cyclohexane ring affects the antitumor activity.

Potential Antitumor

Discovery of the antitumor activity of platinum complex, cisplatin, cis-Pt(NH3)2Cl2, and later carboplatin and oxaliplatin, led to the intensive investigation of the potential antitumor activity of the huge number of platinum complexes. Furthermore, it is well-known that platinum complexes express toxicity, numerous side effects and resistance, so the scientists make a lot of efforts to synthetize, beside Pt(II) and Pt(IV), other non-platinum compounds with potential antitumor activity, such as Pd(II), Ru(II/III) and Au(III) complexes. The goal of this study is to summarize the results of the investigation of the interactions between some mononuclear, homo- and hetero-polynuclear Pt(II), Pd(II), Ru(II/III) and Au(III) complexes with different sulfur- and nitrogen-donor biologically relevant nucleophiles. Among mononuclear complexes, the compounds with aromatic terpy (tepyridine) or bpma (bis-(2- pyridylmethyl)amine) and aliphatic dien (diethylentriamine) nitrogen-containing inert ligands were studied. Different homo- and hetero-polynuclear complexes with pz (pyrazine) or 4,4’-bipy (4,4’- bipyridine) as bridging and mostly en (ethylenediamine), bipy (2,2’-bipyridine) and dach (trans-1,2- diaminocyclohexane) as inert ligands were studied as well. The research was focused on the connection between the structure and the mechanisms of interactions with different biomolecules, such as L- cysteine (L-Cys), L-methionine (L-Met), tripeptide glutathione (GSH), guanosine-5’-monophosphate (5’-GMP), DNA and bovine serum albumin (BSA). Some of these complexes were selected for in vitro studies of the cytotoxicity on different tumor cell lines. Observed results contribute a lot as a guidance for the future design and determination of the structure-activity relationship (SAR) of different transition metal ion complexes.

Digoxin is a cardiac glycoside long used to treat congestive heart failure and found recently to show antitumor potential. The hydroxy groups connected at the C-12, C-14, and C-3′a positions; the C-17 unsaturated lactone unit; the conformation of the steroid core; and the C-3 saccharide moiety have been demonstrated as being important for digoxin’s cytotoxicity and interactions with Na+/K+-ATPase. The docking profiles for digoxin and several derivatives and Na+/K+-ATPase were investigated; an additional small Asn130 side pocket was revealed, which could be useful in the design of novel digoxin-like antitumor agents. In addition, the docking scores for digoxin and its derivatives were found to correlate with their cytotoxicity, indicating a potential use of these values in the prediction of the cancer cell cytotoxicity of other cardiac glycosides. Moreover, in these docking studies, digoxin was found to bind to FIH-1 and NF-κB but not HDAC, IAP, and PI3K, suggesting that this cardiac glycoside directly targets FIH-1, Na+/K+-ATPase, and NF-κB to mediate its antitumor potential. Differentially, digoxigenin, the aglycon of digoxin, binds to HDAC and PI3K, but not FIH-1, IAP, Na+/K+-ATPase, and NF-κB, indicating that this compound may target tumor autophagy and metabolism to mediate its antitumor propensity.

Scaffolds hybridization is a well-known drug design strategy for antitumor agents. Herein, series of novel indolyl-pyrimidine hybrids were synthesized and evaluated in vitro and in vivo for their antitumor activity. The in vitro antiproliferative activity of all compounds was obtained against MCF-7, HepG2, and HCT-116 cancer cell lines, as well as against WI38 normal cells using the resazurin assay. Compounds 1–4 showed broad spectrum cytotoxic activity against all these cancer cell lines compared to normal cells. Compound 4g showed potent antiproliferative activity against these cell lines (IC50 = 5.1, 5.02, and 6.6 μM, respectively) comparable to the standard treatment (5-FU and erlotinib). In addition, the most promising group of compounds was further evaluated for their in vivo antitumor efficacy against EAC tumor bearing mice. Notably, compound 4g showed the most potent in vivo antitumor activity. The most active compounds were evaluated for their EGFR inhibitory (range 53–79 %) activity. Compound 4g was found to be the most active compound against EGFR (IC50 = 0.25 µM) showing equipotency as the reference treatment (erlotinib). Molecular modeling study was performed on compound 4g revealed a proper binding of this compound inside the EGFR active site comparable to erlotinib. The data suggest that compound 4g could be used as a potential anticancer agent.

Two series of olmutinib derivatives containing an acrylamide moiety were designed and synthesized, and their IC50 values against cancer cell lines (A549, H1975, NCI-H460, LO2, and MCF-7) were evaluated. Most of the compounds exhibited moderate cytotoxic activity against the five cancer cell lines. The most promising compound, H10, showed not only excellent activity against EGFR kinase but also positive biological activity against PI3K kinase. The structure–activity relationship (SAR) suggested that the introduction of dimethylamine scaffolds with smaller spatial structures was more favorable for antitumor activity. Additionally, the substitution of different acrylamide side chains had different effects on the activity of compounds. Generally, compounds H7 and H10 were confirmed as promising antitumor agents.
