Abstract
An inclusion system of embedding ferulic acid into β-cyclodextrin (FACD) with different host-guest stoichiometries was prepared by a co-precipitation method. Then, the physicochemical properties and release kinetics of the FACD were evaluated. The results of thermal analysis, X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy (FTIR) proved the successful embedding of FA into the β-cyclodextrin matrix. Four mathematical models were applied to adjust the ferulic acid release profile and identify preferential kinetics. The results of physicochemical properties confirmed the successful formation of the complexes. The loading capacity (LC) and encapsulation efficiency (EE) of the inclusion complex (1 : 0.5) were 41.0 ± 3.28 mg g-1 and 52.1 ± 2.31%, respectively, which were significantly higher than other molar ratios. The release behaviour revealed that loaded FA molecules under various host-guest stoichiometries obey different release models. While lower host-guest stoichiometry (1 : 0.5) provided desirable EE, the moderate host-guest stoichiometry (1 : 1) exhibited faster release behaviour. The FACD inclusion complex could be a promising bioactive material for food preservation.

Abstract
Terpenes constitute the largest class of natural products and are important resources for the pharmaceutical, food and cosmetics industries. However, due to their low water solubility and poor bioavailability there has been a search for compounds that could improve their physicochemical properties. Cyclodextrins (natural and derived) have been proposed for this role and have been complexed with different types of terpenes. This complexation has been demonstrated by using analytical techniques for characterizing complexes such as DSC, NMR, XRD, FTIR, and TGA. The formation of inclusion complexes has been able to improve drug characteristics such as bioavailability, solubility and stability; and to enhance biological activity and efficacy. This review shows strong experimental evidence that cyclodextrins improve the pharmacological properties of terpenes, and therefore need to be recognized as being possible targets for clinical use.

Abstract
A novel series of artesunate-β-cyclodextrin (ATS-β-CD) conjugates, in which artesunate (ATS) was coupled covalently to one of the primary hydroxyl groups of β-cyclodextrin (β-CD) through amino bond formation, were synthesized and characterized by (1)H NMR, HRMS, 2D NMR (ROESY), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The results showed that the aqueous solubility of ATS-β-CD conjugates was 26-45 times better than that of free ATS. The cytotoxicity of the ATS-β-CD conjugates was evaluated on human colon cancer cell lines HCT116, LOVO, SW480, and HT-29, and the results indicated that ATS-2NβCD exhibited a very high cytotoxicity against HCT116, LOVO, and HT-29 with IC50 values of 0.58, 1.62, and 5.18μmol/L, respectively. In addition, the supposition of better cytotoxicity was further supported by the control experiment of fluorescent cyclodextrin.

Abstract
Malaria is an infectious disease that mainly affects children and pregnant women from tropical countries. The mortality rate of people infected with malaria per year is enormous and became a public health concern. The main factor that has contributed to the success of malaria proliferation is the increased number of drug resistant parasites. To counteract this trend, research has been done in nanotechnology and nanomedicine, for the development of new biocompatible systems capable of incorporating drugs, lowering the resistance progress, contributing for diagnosis, control and treatment of malaria by target delivery. In this review, we discussed the main problems associated with the spread of malaria and the most recent developments in nanomedicine for anti-malarial drug delivery.

Abstract
Inclusion of artesunate in the cavity of β-cyclodextrin (β-CD) as well as its methyl and hydroxypropyl derivatives was investigated experimentally and by molecular modeling studies. The effect of PEG on the inclusion was also studied. A 1:1 stoichiometry was indicated by phase-solubility studies both in the presence and absence of PEG and suggested by the mass spectrometry. The mode of inclusion was supported by 2D NMR and results were further verified by docking studies utilizing Fast Rigid Exhaustive Docking acronym. The thermodynamic parameters were determined for both binary and ternary systems using solution calorimetry and were found to be best for the methyl-β-cyclodextrin (Me-β-CD) system. However, the presence of PEG improves the complexation ability as evident from elevation in the numerical value of the stability constant (K). Solubility and dissolution profile of binary complex is enhanced in the presence of PEG, which is approximately at par with drug Me-β-CD complexes. In vivo studies showed 100% survivability in artesunate-Me-β-CD complexes.

Abstract
Despite the fact that we live in an era of advanced technology and innovation, infectious diseases, like malaria, continue to be one of the greatest health challenges worldwide. The main drawbacks of conventional malaria chemotherapy are the development of multiple drug resistance and the non-specific targeting to intracellular parasites, resulting in high dose requirements and subsequent intolerable toxicity. Nanosized carriers have been receiving special attention with the aim of minimizing the side effects of drug therapy, such as poor bioavailability and the selectivity of drugs. Several nanosized delivery systems have already proved their effectiveness in animal models for the treatment and prophylaxis of malaria. A number of strategies to deliver antimalarials using nanocarriers and the mechanisms that facilitate their targeting to Plasmodium spp.-infected cells are discussed in this review. Taking into account the peculiarities of malaria parasites, the focus is placed particularly on lipid-based (e.g., liposomes, solid lipid nanoparticles and nano and microemulsions) and polymer-based nanocarriers (nanocapsules and nanospheres). This review emphasizes the main requirements for developing new nanotechnology-based carriers as a promising choice in malaria treatment, especially in the case of severe cerebral malaria.

Abstract
A recent therapeutic index study in rats demonstrated that i.v. artesunate (AS) is safer than artelinate (AL). The present study of acute toxicity illustrated an LD(50) of 177 mg/kg and 488 mg/kg for AL and AS, respectively, following daily i.v. injection for 3 days in Plasmodium berghei-infected rats. In uninfected rats, the LD(50) values were 116 mg/kg and 351 mg/kg after a single dose of AL and AS, respectively. This study showed vascular necrosis in 50% of the animals at 13.5 mg/kg AL and at 42.8 mg/kg AS. Animals also showed moderate signs of renal failure at 40 mg/kg AL and 240 mg/kg AS (100 times higher than the therapeutic dose). Histopathological evaluation demonstrated mild to moderate tubular necrosis in uninfected rats treated with 40 mg/kg AL and 240 mg/kg AS; interestingly, fewer pathological lesions were observed in malaria-infected rats. Renal injury was reversible in all cases by Day 8 after cessation of dosing. No neurotoxicity was seen in any case with all i.v. regimens. In conclusion, AL and AS exhibit less toxic effects in P. berghei-infected rats than in uninfected rats. Both agents caused irreversible vascular irritation, reversible nephrotoxicity and no neurotoxicity at high doses. The data indicate that AS is three times safer than AL in rats.

Abstract
The current studies were undertaken to explore the potential basis for a significant difference in the pharmacokinetic parameters after intravenous administration of a synthetic ozonide (OZ) antimalarial drug candidate (1) to rats when formulated in either Captisol (a sulfobutylether substituted beta-cyclodextrin derivative ((SBE)(7)-beta-CD)) or a buffered aqueous vehicle. It was suspected that the differences may have been due to failure of 1 to rapidly dissociate from the cyclodextrin complex in vivo, perhaps due to an unusually tight binding within the cyclodextrin cavity. To address this hypothesis, the binding of representative synthetic OZ antimalarial drug candidates (including 1) with beta-cyclodextrin and (SBE)(7)-beta-CD was investigated by isothermal titration calorimetry and phase solubility analysis. It was found that each of the OZ compounds exhibited an exceptionally high binding constant ( approximately 10(6)/M) with both Cyclodextrins (CD). The nature of the complexation was investigated by molecular dynamics simulations and NMR to explore the mechanisms, which generated such high binding constants. The data suggested that the most probable cause of the unusually high binding constants was a very close fit within the cyclodextrin cavity that resulted in more favourable changes in both the enthalpy and entropy of the binding interaction, compared to published data for other drugs.
