Cancer, a highly heterogeneous disease at intra/inter patient levels, is one of the most serious threats to human health across the world [1, 2]. Notwithstanding the noteworthy advances in its treat-ment, the morbidity and mortality of cancer are projected to grow for a long period, and the global cancer burden is expected to be 28.4 million cases in 2040, a 47% rise from 2020 [3]. Accordingly, there is a constant need to explore novel anticancer agents. <p> There are several strategies to discover novel anticancer candidates: (1) new lead hits or candidates from natural resources [4] whichexhibit various biological properties and are a rich source of com-pounds in drug discovery due to the structural and mechanistic diversity, and more than 60% anti-cancer agents can be traced to a natural product; (2) Molecular hybridization is one of the most prom-ising strategies for the discovery of novel anticancer drug candidates since hybrid molecules have the potential to bind multiple targets or to enhance the effect through acting with another bio-target or to counterbalance the side effects caused by the other part of the hybrid [5]; (3) Dimerization is a useful tool to develop novel anticancer drug candidates with enhanced biological activity, reduced side effects and improved pharmacokinetic profiles [6]; (4) Drug repurposing strategy is is an attractive strategy and has been approved, along with non-anticancer macrolide drugs for the treatment of cancer, for anticancer drug discovery since toxicity and pharmacokinetic profiles have already been estab-lished [7]. <p> Heterocycles coumarin, β-lactone, macrolide and triazole are useful anticancer pharmacophores since their derivatives could exert the anticancer activity through diverse mechanisms, inclusive of inhibition of aromatase, carbonic anhydrase, ki-nase, P-glycoprotein, sulfatase, telomerase, vascular endothelial growth factor receptor 2 and tubulin [8-11]. In particular, nat-ural-derived coumarin, β-lactone and macrolide derivatives are important sources of new anticancer lead hits/candidates; mac-rolide repurposed drugs can circumvent high cost and long-time associated with traditional drug discovery strategies; couma-rin, β-lactone and macrolide hybrids as well as bis-triazole compounds have the potential to enhance the anticancer activity, overcome drug resistance, reduce the side effects and improve pharmacokinetic profiles.

Background: Reckoning molecular topological indices of drug structures gives the data about the underlying topology of these drug structures. Novel anticancer drugs have been leading by researchers to produce ideal drugs. Materials and Methods: Pharmacological properties of these new drug agents explored by utilizing simulation strategies. Topological indices additionally have been utilized to research pharmacological properties of some drug structures. Novel alkylating agents based anticancer drug candidates and ve-degree molecular topological indices have been introduced recently. Results and Conclusion: In this study we calculate ve-degree atom-bond connectivity, harmonic, geometric-arithmetic and sum-connectivity molecular topological indices for the newly defined alkylating agents based dual-target anticancer drug candidates.

Background: Cucurbitacins belong to a group of tetracyclic triterpenoids that display a wide range of biological effects. In the past, numerous cucurbitacins have been isolated from natural sources and many active compounds have been synthesized using the privileged scaffold in order to enhance its cytotoxic effects. Objective: his review covers patents on the therapeutic effects of natural cucurbitacins and their synthetic analogs published during the past decade. By far, the majority of patents published are related to cancer and Structure-Activity Relationships (SAR) of these compounds are included to lend gravitas to this important class of natural products. Methods: The date about the published patents was downloaded via online open access patent databases. Results: Cucurbitacins display significant cytotoxic properties, in particular cucurbitacins B and D which possess very potent effects towards a number of cancer cells. Numerous cucurbitacins isolated from natural sources have been derivatized through chemical modification at the C(2)-OH and C(25)- OH groups. Most importantly, an acyl ester of the C(25)-OH and, iso-propyl, n-propyl and ethyl ether groups of the C(2)-OH demonstrated the most increased cytotoxic activity. Conclusion: The significant cytotoxic effects of natural and semi-synthetic cucurbitacins make them attractive as new drug candidates. Moreover, cucurbitacins have the capability to form conjugates with other anticancer drugs which will synergistically enhance their anticancer effects. The authors believe that in order to get lead compounds, there should be a greater focus on the synthesis of homodimers, heterodimers, and halo derivatives of cucurbitacins. In the opinion of the authors the analysis of the published patents on the cucurbitacins indicates that these compounds can be developed into a regimen to treat a wide spectrum of cancers.

We synthesized a novel anticancer agents based on mixed chelate copper (II) complexes, named Casiopeínas® has of general formula [Cu(N-N)(N-O)H2O]NO3 (where, N-N = diimines as 1,10- phenanthroline, 2,2-bipyridine, or substituted and N-O=aminoeidate or [Cu(N-N)(O-O)H2O]NO3 (where NN= diimines as 10-phenanthroline, 2,2-bipyridine or substituted Casiopeínas I, II, IV, V, VI, VII VIII and O-O=acetylacetonate, salicylaldehidate Casiopínas III). We evaluated the in vitro antitumor activity using a human cancer cell panel and some nurine cancer cells. Eleven Casiopeinas are evaluated in order to acquire some structure-activity correlations and some monodentated Casiopeinäs analogues; cisplatinum was used as control drug. The 50% growth inhibition observed is, in all cases reach with concentrations of Casiopeina's 10 or 100 times lower than cisplatinum. In a previous work we reported the induction of apoptosis by Casiopeina II. The results indicate that Casiopeinass are a promising new anticancer drug candidates to be developed further toward clinical trials.
