Abstract
Background:
2,4-disubstituted-1,3-thiazole derivatives (2a–j), (3a–f) and (4a–f) were
synthesized, characterized and screened for their potential as antimicrobial agents. In the preliminary
screening against a panel of bacterial strains, nine compounds showed moderate to potent antibacterial
activity (IC50 = 13.7-90.8 μg/ml).
</P><P>
Methods: In the antifungal screening, compound (4c) displayed potent antifungal activity
(IC50 = 26.5 µg/ml) against Candida tropicalis comparable to the standard drug, fluconazole
(IC50 = 10.5 µg/ml). Based on in vitro antimicrobial results, compounds 2f, 4c and 4e were selected
for further pharmacological investigations. Hemolytic activity using human red blood cells
(hRBCs) and cytotoxicity by MTT assay on human embryonic kidney (HEK-293) cells revealed
non-toxic nature of the selected compounds (2f, 4c and 4e). To ascertain their possible mode
of action, docking studies with the lead inhibitors (2f, 4c and 4e) were performed using crystal
structure coordinates of bacterial methionine aminopeptidases (MetAPs), an enzyme involved in
bacterial protein synthesis and maturation.
Results:
The results of in vitro and in silico studies provide a rationale for selected compounds (2f,
4c and 4e) to be carried forward for further structural modifications and structure-activity relationship
(SAR) studies against these bacterial infections.
Conclusion:
The study suggested binding with one or more key amino acid residues in the active
site of Streptococcus pneumoniae MetAP (SpMetAP) and Escherichia coli MetAP (EcMetAP). In
silico physicochemical properties using QikProp confirmed their drug likeliness.

Abstract
Despite the vast availability of antibiotics, bacterial infections remain a leading cause of death worldwide. In an effort to enhance the armamentarium against resistant bacterial strains, 1,2,3-triazole (5a-x) and sulfonate (7a-j) analogues of natural bioactive precursors were designed and synthesized. Preliminary screening against two Gram-positive (Streptococcus pneumoniae and Enterococcus faecalis) and four Gram-negative bacterial strains (Pseudomonas aeruginosa, Salmonella enterica, Klebsiella pneumoniae, and Escherichia coli) was performed to assess the potency of these analogues as antibacterial agents. Among all triazole analogues, 5e (derived from carvacrol) and 5u (derived from 2-hydroxy 1,4-naphthoquinone) bearing carboxylic acid functionality emerged as potent antibacterial agents against S. pneumoniae (IC50: 62.53 and 39.33 μg/mL), E. faecalis (IC50: 36.66 and 61.09 μg/mL), and E. coli (IC50: 15.28 and 22.57 μg/mL). Furthermore, 5e and 5u also demonstrated moderate efficacy against multidrug-resistant E. coli strains and were therefore selected for further biological studies. Compound 5e in combination with ciprofloxacin displayed a synergistic effect on multidrug-resistant E. coli MRA11 and MRC17 strains, whereas compound 5u was selective against E. coli MRA11 strain. Growth kinetic studies on S. pneumoniae and E. coli treated with 5e and 5u showed an extended lag phase. 5e and 5u did not show significant cytotoxicity up to 100 μg/mL concentration on human embryonic kidney (HEK293) cells. Transmission electron microscopic (TEM) analysis of bacterial cells (S. pneumoniae and E. coli) exposed to 5e and 5u clearly showed morphological changes and damaged cell walls. Moreover, these compounds also significantly inhibited biofilm formation in S. pneumoniae and E. coli strains, which was visualized by scanning electron microscopic (SEM) analysis. Treatment of larvae of Galleria mellonella (an in vivo model for antimicrobial studies) with 5e and 5u did not cause an alteration in the hemocyte density, thereby indicating lack of an immune response, and were nontoxic up to a concentration of 2.5 mg/mL.

Abstract
The present study describes the synthesis of 1,2,3-triazole–quinazolinone conjugates (5a–q) from ethyl 4-oxo-3-(prop-2-ynyl)-3,4-dihydroquinazoline-2-carboxylate and phenyl azide/substituted phenyl azides employing Cu(i) catalysed Huisgen 1,3-dipolar cycloaddition. The corresponding acids (6a–q) were obtained by hydrolysis of esters (5a–q) to study the effect of these functionalities on the biological activity. All synthesized compounds were screened for in vitro anticandidal evaluation against Candia albicans, Candida glabrata and Candida tropicalis strains. The results indicated that compound 5n showed potent anticandidal activity with IC50 in the range of 8.4 to 14.6 μg mL−1. Hemolytic activity using human red blood cells (hRBCs) and cytotoxicity by MTT assay on human embryonic kidney (HEK-293) cells revealed the non-toxic nature of the selected compounds. Growth kinetic study with compound 5n showed its fungicidal nature as no significant growth of Candida cells was observed even after 24 h. Cellular ergosterol content was determined in the presence of different concentrations of 5n to measure the activity of lanosterol 14α-demethylase indirectly. The results showed significant disruption of the ergosterol biosynthetic pathway through inhibition of lanosterol 14α-demethylase activity supported by docking studies (PDB: 5v5z). Overall, this study demonstrates the anticandidal potential of 5n which can serve as the lead for further structural optimization and SAR studies. The present study elicits the synthesis of 1,2,3-triazole–quinazolinone conjugates (5a–q) as ergosterol inhibitors for Candida infections.![]()

Abstract
Human calcium/calmodulin-dependent protein kinase IV (CAMKIV) is a member of Ser/Thr kinase family, and is associated with different types of cancer and neurodegenerative diseases. Vanillin is a natural compound, a primary component of the extract of the vanilla bean which possesses varieties of pharmacological features including anti-oxidant, anti-inflammatory, anti-bacterial and anti-tumor. Here, we have investigated the binding mechanism and affinity of vanillin to the CAMKIV which is being considered as a potential drug target for cancer and neurodegenerative diseases. We found that vanillin binds strongly to the active site cavity of CAMKIV and stabilized by a large number of non-covalent interactions. We explored the utility of vanillin as anti-cancer agent and found that it inhibits the proliferation of human hepatocyte carcinoma (HepG2) and neuroblastoma (SH-SY5Y) cells in a dose-dependent manner. Furthermore, vanillin treatment resulted into the significant reduction in the mitochondrial membrane depolarization and ROS production that eventually leads to apoptosis in HepG2 and SH-SY5Y cancer cells. These findings may offer a novel therapeutic approach by targeting the CAMKIV using natural product and its derivative with a minimal side effect.

Abstract
Mycobacterium tuberculosis is responsible for severe mortality and morbidity worldwide but, under-developed and developing countries are more prone to infection. In search of effective and wide-spectrum anti-tubercular agents, interdisciplinary approaches are being explored. Of the several approaches used, computer based quantitative structure activity relationship (QSAR) have gained momentum. Structure-based drug design and discovery implies a combined knowledge of accurate prediction of ligand poses with the good prediction and interpretation of statistically validated models derived from the 3D-QSAR approach. The validated models are generally used to screen a small combinatorial library of potential synthetic candidates to identify hits which further subjected to docking to filter out compounds as novel potential emerging drug molecules to address multidrug-resistant tuberculosis. Several newer models are integrated to QSAR methods which include different types of chemical and biological data, and simultaneous prediction of pharmacological activities including toxicities and/or other safety profiles to get new compounds with desired activity. In the process, several newer molecules have been identified which are now being assessed for their clinical efficacy. Present review deals with the advances made in the field highlighting overall future prospects of the development of anti-tuberculosis drugs.

Abstract
According to WHO, leishmaniasis is a major tropical disease, ranking second after malaria. Significant efforts have been therefore invested into finding potent inhibitors for the treatment. In this work, eighteen novel 1,2,3-triazoles appended with l-amino acid (Phe/Pro/Trp) tail were synthesized via azide-alkyne click chemistry with moderate to good yield, and evaluated for their anti-leishmanial activity against promastigote form of Leishmania donovani (Dd8 strain). Among all, compounds 40, 43, and 53 were identified with promising anti-leishmanial activity with IC50=88.83±2.93, 96.88±12.88 and 94.45±6.51μM respectively and displayed no cytotoxicity towards macrophage cells. Moreover, compound 43 showed highest selectivity index (SI=8.05) among all the tested compounds. Supported by docking studies, the lead inhibitors (40, 43 and 53) showed interactions with key residues in the catalytic site of trypanothione reductase. The results of pharmacokinetic parameters suggest that these selected inhibitors can be carried forward for further structural optimization and pharmacological investigation.

Abstract
Human microtubule affinity-regulating kinase 4 (MARK4) is considered as an encouraging drug target for the design and development of inhibitors to cure several life-threatening diseases such as Alzheimer disease, cancer, obesity, and type-II diabetes. Recently, we have reported four ligands namely, BX-912, BX-795, PKR-inhibitor, and OTSSP167 (hydrochloride) which bind preferentially to the two different constructs of human MARK4 containing kinase domain. To ensure the role of ubiquitin-associated (UBA) domain in the ligand binding, we made a newer construct of MARK4 which contains both kinase and UBA domains, named as MARK4-F3. We observed that OTSSP167 (hydrochloride) binds to the MARK4-F3 with a binding constant (K) of 3.16 × 106, M-1 (±.21). However, UBA-domain of MARK4-F3 doesn't show any interaction with ligands directly as predicted by the molecular docking. To validate further, ATPase inhibition assays of all three constructs of MARK4 in the presence of mentioned ligands were carried out. An appreciable correlation between the binding experiments and ATPase inhibition assays of MARK4 was observed. In addition, cell-proliferation inhibition activity for all four ligands on the Human embryonic kidney (HEK-293) and breast cancer cell lines (MCF-7) was performed using MTT assay. IC50 values of OTSSP167 for HEK-293 and MCF-7 were found to be 58.88 (±1.5), and 48.2 (±1.6), respectively. OTSSP167 among all four inhibitors, showed very good enzyme inhibition activity against three constructs of MARK4. Moreover, all four inhibitors showed anti-neuroblastoma activity and anticancer properties. In conclusion, OTSSP167 may be considered as a promising scaffold to discover novel inhibitors of MARK4.

Abstract
The increasing incidence of human candidiasis and the tendency of Candida species to become resistant to existing chemotherapies are well-recognized health problems. The present study demonstrates the successful synthesis of novel triazole-amino acid hybrids with potent in vitro and in vivo inhibitory activity against Candida species. Particularly, compounds 68 and 70 showed potent in vitro activity against fluconazole (FLC) resistant as well as sensitive clinical isolates of Candida albicans. Time kill curve analysis of lead inhibitors 68 and 70 showed their fungistatic nature. Secretion of hydrolytic enzymes, mainly proteinases and phospholipases, decreased considerably in the presence of 68 and 70 indicating their interference in fungal virulence. TEM analysis of Candida cells exposed to compounds 68 and 70 clearly showed morphological changes and intracellular damage as their possible mode of action. A preliminary mechanistic study carried out on the two most effective inhibitors (68 and 70) revealed the inhibition of ergosterol biosynthesis thereby causing the cells to lose their integrity and viability. The selected compounds did not show significant cytotoxicity up to a concentration of 200 μg mL-1 in the HEK293 cell line. An in silico analysis of 68 and 70 binding to a modeled C. albicans CYP51 showed critical H-bonding as well as hydrophobic interactions with the important active site residues indicating the basis of their anti-Candida role. Studies on the larvae of Galleria mellonella showed that the selected inhibitors (68 and 70) were non-toxic, did not provoke an immune response and significantly reduced Candida proliferation in vivo.

Designing New Kinase Inhibitor Derivatives as Therapeutics Against Common Complex Diseases: Structural Basis of Microtubule Affinity-Regulating Kinase 4 (MARK4) Inhibition.

Abstract
Drug development for common complex diseases is in need of new molecular entities and actionable drug targets. MAP/microtubule affinity-regulating kinase 4 (MARK4) is associated with numerous diseases such as neurodegenerative disorders, obesity, cancer, and type 2 diabetes. Understanding the structural basis of ligands' (inhibitors) and substrates' binding to MARK4 is crucial to design new kinase inhibitors for therapeutic purposes. This study reports new observations on docking three well-known kinase inhibitors in the kinase domain of MARK4 variants and the calculated binding affinity. These variants of MARK4 are named as MARK4-F1 (59 N-terminal residues along with kinase domain) and MARK4-F2 (kinase domain of MARK4). We additionally performed molecular dynamics (MD) simulation and fluorescence binding studies to calculate the actual binding affinity of kinase inhibitors, BX-912, BX-795, and OTSSP167 (hydrochloride) for the MARK4. Docking analyses revealed that ligands bind in the large hydrophobic cavity of the kinase domain of MARK4 through several hydrophobic and hydrogen-bonded interactions. Simulations suggested that OTSSP167 (hydrochloride) is forming a stable complex, and hence the best inhibitor of MARK4. Intrinsic fluorescence of MARK4 was significantly quenched by addition of ligands, indicating their potential binding to MARK4. A lower KD value of MARK4 with OTSSP167 (hydrochloride) suggested that it is a better interacting partner than BX-912 and BX-795. These data form a basis for designing novel and potent OTSSP167 (hydrochloride) derivatives as therapeutic candidates against common complex diseases. The inhibitors designed as such might possibly suppress the growth of tumor-forming cells and be potentially applied for treatment of a wide range of human cancers as well.
