Abstract
Aim: Discovery of novel SARS-CoV-2 main protease (Mpro) inhibitors using a structure-based drug discovery strategy. Materials & methods: Virtual screening employing covalent and noncovalent docking was performed to discover Mpro inhibitors, which were subsequently evaluated in biochemical and cellular assays. Results: 91 virtual hits were selected for biochemical assays, and four were confirmed as reversible inhibitors of SARS CoV-2 Mpro with IC50 values of 0.4-3 μM. They were also shown to inhibit SARS-CoV-1 Mpro and human cathepsin L. Molecular dynamics simulations indicated the stability of the Mpro inhibitor complexes and the interaction of ligands at the subsites. Conclusion: This approach led to the discovery of novel thiosemicarbazones as potent SARS-CoV-2 Mpro inhibitors.

Abstract
Abstract
Background
Conduction system pacing (CSP) (His bundle pacing and left bundle pacing) is a group of techniques intended to achieve cardiac pacing with a narrow QRS complex through a lead directly inserted in conduction system structures. The safety and effectiveness of this technique are not yet fully understood.
Purpose
To describe the short-term implant findings and safety profile of CSP as a first option after 4 years in a single center.
Methods
In a period of 42 months, 214 patients were submitted to CSP as a first strategy to restore AV synchrony (pacemakers for AV block or sinus node dysfunction) or as a resynchronization (CRT) strategy (for patients with heart failure and bundle branch block). CSP lead was implanted in lieu of a conventional right ventricular lead in pacemaker cases, and in addition or in lieu of a coronary sinus lead, in CRT cases, depending on the technical and anatomical possibilities.
Results
The mean age was 76.7±16.4 years, 65% males. 162 patients implanted a CSP lead for a dual-chamber pacemaker, 3 patients for a single chamber pacemaker, 32 patients for CRT-D (CSP lead replacing the coronary sinus lead with a defibrillator), and 13 patients for an optimized CRT (CSP lead plus coronary sinus lead). In 16 patients (7.4%) the technique of choice was His bundle pacing, two of them presented with subacute elevated thresholds, requiring new lead implantation at the moment of generator pulse replacement. One patient submitted to left bundle branch pacing (0.4%) had subacute lead dislodgement, being submitted to lead revision. Four patients intended for CRT (1.8%) didn't meet the criteria for His bundle pacing or left bundle branch pacing, being submitted to conventional coronary sinus lead placement. There were 10 cases (4.6%) of confirmed lead perforation during the lead septum insertion, with prompt repositioning, all uneventful. No pericardium effusion related to lead perforation was observed. One patient (0.4%) had a pneumothorax, requiring chest tube drainage.
Conclusion
Conduction system pacing as a first strategy is a feasible, effective and safe technique, both for pacing and for resynchronization purposes, with a complication rate comparable to conventional implantation.

Abstract
Cruzain, the main cysteine protease of Trypanosoma cruzi, plays key roles in all stages of the parasite's life cycle, including nutrition acquisition, differentiation, evasion of the host immune system, and invasion of host cells. Thus, inhibition of this validated target may lead to the development of novel drugs for the treatment of Chagas disease. In this study, a multiparameter optimization (MPO) approach, molecular modeling, and structure-activity relationships (SARs) were employed for the identification of new benzimidazole derivatives as potent competitive inhibitors of cruzain with trypanocidal activity and suitable pharmacokinetics. Extensive pharmacokinetic studies enabled the identification of metabolically stable and permeable compounds with high selectivity indices. CYP3A4 was found to be involved in the main metabolic pathway, and the identification of metabolic soft spots provided insights into molecular optimization. Compound 28, which showed a promising trade-off between pharmacodynamics and pharmacokinetics, caused no acute toxicity and reduced parasite burden both in vitro and in vivo.

Abstract
Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi that endangers almost 70 million people worldwide. The only two drugs that are currently approved for its treatment, benznidazole and nifurtimox, have controversial efficacy in adults and restricting safety issues, leaving thousands of patients without a suitable treatment. The neglect of Chagas disease is further illustrated by the lack of a robust and diverse drug discovery and development portfolio of new chemical entities, and it is of paramount importance to build a strong research and development network for antichagasic drugs. Focusing on drug discovery programs led by scientists based in Latin America, the main endemic region for this disease, we discuss herein what has been published in the last decade in terms of identification of new antiparasitic drugs to treat Chagas disease, shining a spotlight on the origin, chemical diversity, level of characterization of hits, and strategies used for optimization of lead compounds. Finally, we identify strengths and weaknesses in these drug discovery campaigns and highlight the importance of multidisciplinary collaboration and knowledge sharing.

Abstract
A series of benzene sulphonamides with good potency and selectivity against Leishmania spp. intracellular amastigotes was identified by high-throughput screening. Approximately 200 compounds were synthesized as part of a hit-to-lead optimization program. The potency of the series appears to be strongly dependent on lipophilicity, making the identification of suitable orally available candidates challenging due to poor pharmacokinetics. Despite not identifying a clinical candidate, a likely solvent exposed area was found, best exemplified in compound 29. Ongoing detailed mode-of-action studies may provide an opportunity to use target-based medicinal chemistry to overcome the issues with the current series.

Abstract
Chagas disease causes ~10,000 deaths each year, mainly in Latin America, where it is endemic. The currently available chemotherapeutic agents are ineffective in the chronic stage of the disease, and the lack of pharmaceutical innovation for Chagas disease highlights the urgent need for the development of new drugs. The enzyme cruzain, the main cysteine protease of Trypanosoma cruzi, has been explored as a validated molecular target for drug discovery. Herein, the design, molecular modeling studies, synthesis, and biological evaluation of cyclic imides as cruzain inhibitors are described. Starting with a micromolar-range cruzain inhibitor (3a, IC50 = 2.2 μM), this molecular optimization strategy resulted in the nanomolar-range inhibitor 10j (IC50 = 0.6 μM), which is highly active against T. cruzi intracellular amastigotes (IC50 = 1.0 μM). Moreover, most compounds were selective toward T. cruzi over human fibroblasts, which were used as host cells, and are less toxic to hepatic cells than the marketed drug benznidazole. This study enabled the discovery of novel chemical diversity and established robust structure-activity relationships to guide the design of optimized cruzain inhibitors as new trypanocidal agents.

Abstract
The structure-activity relationship of a 4-Azaindole-2-piperidine compound selected from GlaxoSmithKline's recently disclosed open-resource "Chagas box" and possessing moderate activity against Trypanosoma cruzi, the parasite responsible for Chagas disease, is presented. Despite considerable medicinal chemistry efforts, a suitably potent and metabolically stable compound could not be identified to advance the series into in vivo studies. This research should be of interest to those in the area of neglected diseases and in particular anti-kinetoplastid drug discovery.

Abstract
The development of cruzain inhibitors has been driven by the urgent need to develop novel and more effective drugs for the treatment of Chagas' disease. Herein, we report the lead optimization of a class of noncovalent cruzain inhibitors, starting from an inhibitor previously cocrystallized with the enzyme (K(i) = 0.8 μM). With the goal of achieving a better understanding of the structure-activity relationships, we have synthesized and evaluated a series of over 40 analogues, leading to the development of a very promising competitive inhibitor (8r, IC50 = 200 nM, K(i) = 82 nM). Investigation of the in vitro trypanocidal activity and preliminary cytotoxicity revealed the potential of the most potent cruzain inhibitors in guiding further medicinal chemistry efforts to develop drug candidates for Chagas' disease.

Abstract
AIM To identify and quantify mast cell (MC), vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) in human periapical cysts and granulomas. METHODOLOGY Archived samples of cysts (n = 40) and granulomas (n = 28) were sectioned and stained with toluidine blue. MCs were identified and counted. Immunohistochemical reactions were employed to evaluate the tissue expression of VEGF and vessels. MVD was estimated by determining the areas of tissue labelled with CD31 antibody. The data were analysed using the Mann-Whitney test (P < 0.05). RESULTS MCs were observed in the peripheral regions of both lesion types, whilst VEGF and MVD were distributed in the stroma. The presence of MCs was higher in cysts than in granulomas (P < 0.05). VEGF and MVD expression were similar in these lesions. CONCLUSIONS The highest number of MCs was observed in cysts. Moreover, the identification of VEGF and MVD was consistent with the immune mechanisms involved in the lesions.

Abstract
Migrastatin, a macrolide natural product, and its structurally related analogs are potent inhibitors of cancer cell metastasis, invasion and migration. In the present work, a specialized fragment-based method was employed to develop QSAR models for a series of migrastatin and isomigrastatin analogs. Significant correlation coefficients were obtained (best model, q2 = 0.76 and r2 = 0.91) indicating that the QSAR models possess high internal consistency. The best model was then used to predict the potency of an external test set, and the predicted values were in good agreement with the experimental results (R2 pred = 0.85). The final model and the corresponding contribution maps, combined with molecular modeling studies, provided important insights into the key structural features for the anticancer activity of this family of synthetic compounds based on natural products.

Abstract
A short and efficient approach to a range of new chiral and achiral functionalized (E)-enaminopyran-2,4-diones starting with commercially available dehydroacetic acid is described. The phytotoxic properties of these (E)-enaminopyran-2,4-diones were evaluated by their ability to interfere with the growth of Sorghum bicolor and Cucumis sativus seedlings. A different sensitivity of the two crops was evident with the (E)-enaminopyran-2,4-diones. The most active compounds were also tested against two weeds, Ipomoea grandifolia and Brachiaria decumbens. To the best of our knowledge, this is the first report describing enaminopyran-2,4-diones as potential plant growth regulators.
