THE KEY ROLE OF THE CLINICAL PHARMACIST IN THE MANAGEMENT OF ANTICANCER THERAPIES: A PILOT STUDY IN THE TREATMENT OF PATIENTS WITH NON-SMALL CELL LUNG CANCER
Lung cancer accounts for a quarter of all mortality cases worldwide. To date, numerous efforts have been done to identify the best therapeutic approach, especially in the advanced stage of the disease, and to extend the overall survival of patients. Careful surveillance of patients during therapy is essential in order to identify undesirable effects and to evaluate possible adverse reactions in case of coadministration. This study aims to compare two types of anticancer therapy, immunotherapy and chemotherapy, administered to NSCLC patients in the Medical Oncology Unit of the ARNAS “Di Cristina Benfratelli” Civic Hospital in Palermo (Italy), and to highlight the key role of clinical pharmacist in the management of anticancer therapies, by analysing the side effects in the short-term postadministration and the adverse drug reactions, in particular drug-drug interactions, in case of comorbidities
Marine anticancer agents: An overview with a particular focus on their chemical classes
UID/Multi/04378/2019 IF/00700/2014 grant number 216Z167 grant RTA 2015-00010-C03-02 No. PBA/MB/16/01 PDOC/19/02/01The marine environment is a rich source of biologically active molecules for the treatment of human diseases, especially cancer. The adaptation to unique environmental conditions led marine organisms to evolve different pathways than their terrestrial counterparts, thus producing unique chemicals with a broad diversity and complexity. So far, more than 36,000 compounds have been isolated from marine micro- and macro-organisms including but not limited to fungi, bacteria, microalgae, macroalgae, sponges, corals, mollusks and tunicates, with hundreds of new marine natural products (MNPs) being discovered every year. Marine-based pharmaceuticals have started to impact modern pharmacology and different anti-cancer drugs derived from marine compounds have been approved for clinical use, such as: cytarabine, vidarabine, nelarabine (prodrug of ara-G), fludarabine phosphate (pro-drug of ara-A), trabectedin, eribulin mesylate, brentuximab vedotin, polatuzumab vedotin, enfortumab vedotin, belantamab mafodotin, plitidepsin, and lurbinectedin. This review focuses on the bioactive molecules derived from the marine environment with anticancer activity, discussing their families, origin, structural features and therapeutic use.publishersversionpublishe
Synthesis and Antitumor Activity of New Thiazole Nortopsentin Analogs
New thiazole nortopsentin analogs in which one of the two indole units was replaced by a naphthyl and/or 7-azaindolyl portion, were conveniently synthesized. Among these, three derivatives showed good antiproliferative activity, in particular against MCF7 cell line, with GI50 values in the micromolar range. Their cytotoxic effect on MCF7 cells was further investigated in order to elucidate their mode of action. Results showed that the three compounds act as pro-apoptotic agents inducing a clear shift of viable cells towards early apoptosis, while not exerting necrotic effects. They also caused cell cycle perturbation with significant decrease in the percentage of cells in the G0/G1 and S phases, accompanied by a concomitant percentage increase of cells in the G2/M phase, and appearance of a subG1-cell population

Targeting Multiple Myeloma with natural polyphenols
Multiple myeloma (MM) is still an incurable hematologic malignancy. Although new therapeutic strategies have been developed to target different pathways in malignant cells, such as proliferation, differentiation, and apoptosis, better survival rates have also been achieved by the introduction of autologous stem cell transplantation (ASCT). Hematopoietic stem cell transplantation and novel targeted agents, such as proteasome inhibitors, monoclonal antibodies, immunomodulatory drugs, check-point inhibitors and epigenetic modulators, have significantly achieved long remission time and increased survival rates. However, most patients relapse, develop resistance, and eventually die because of refractorydisease. All these issues highlight the need to investigate newer therapeutic targets to improvepatient outcomes. Natural products play an important role in anti-tumor drug discovery, for this reason,in the investigation of novel natural anti-MM agents, we focused on natural polyphenols. Moreover, plant extracts show no or low toxicity towards normal cells and some of them have also a favorable pharmacokinetic profile. The biological activities of plant extracts are mainly due to their content in polyphenols, flavonoids, and terpenoids. Numerous studies showed that polyphenols, generally recognized as antioxidants, possess anticancer and pro-apoptosis properties. Other studies reported the potential clinical applications of flavonoids for their well-known protective and therapeutic effects against cancer, cardiovascular, and neurodegenerative diseases. The combination of plant extracts with anti-cancer drugs may offer a relevant advantage for therapeutic efficacy by sensitizing malignant cells to drugs and overcoming drug-induced resistance in cancer. For all these reasons, a significant number of polyphenolic compounds isolated from plants are still used nowadays in cancer clinical practice in combination with other drugs, also against hematologic malignancies

Evaluation of Fused Pyrrolothiazole Systems as Correctors of Mutant CFTR Protein
Cystic fibrosis (CF) is a genetic disease caused by mutations that impair the function of the CFTR chloride channel. The most frequent mutation, F508del, causes misfolding and premature degradation of CFTR protein. This defect can be overcome with pharmacological agents named “correctors”. So far, at least three different classes of correctors have been identified based on the additive/synergistic effects that are obtained when compounds of different classes are combined together. The development of class 2 correctors has lagged behind that of compounds belonging to the other classes. It was shown that the efficacy of the prototypical class 2 corrector, the bithiazole corr-4a, could be improved by generating conformationally-locked bithiazoles. In the present study, we investigated the effect of tricyclic pyrrolothiazoles as analogues of constrained bithiazoles. Thirty-five compounds were tested using the functional assay based on the halide-sensitive yellow fluorescent protein (HS-YFP) that measured CFTR activity. One compound, having a six atom carbocyle central ring in the tricyclic pyrrolothiazole system and bearing a pivalamide group at the thiazole moiety and a 5-chloro-2-methoxyphenyl carboxamide at the pyrrole ring, significantly increased F508del-CFTR activity. This compound could lead to the synthesis of a novel class of CFTR correctors
