Abstract
The incidence and mortality of cancer continue to grow since the current medical treatments often fail to produce a complete and durable tumor response and ultimately give rise to therapy resistance and tumor relapse. Heterocycles with potential therapeutic values are of great pharmacological importance, and among them, indazole moiety is a privileged structure in medicinal chemistry. Indazole compounds possess potential anticancer activity, and indazole-based agents such as, axitinib, lonidamine and pazopanib have already been employed for cancer therapy, demonstrating indazole compounds as useful templates for the development of novel anticancer agents. The aim of this review is to present the main aspects of exploring anticancer properties, such as the structural modifications, the structure-activity relationship and mechanisms of action, making an effort to highlight the importance and therapeutic potential of the indazole compounds in the present anticancer agents.

Abstract
Background:
Heterocyclic compounds containing heteroatoms (O, N and S) as part of
five or six-membered cyclic moieties exhibited various potential applications, such as
pharmaceutical drugs, agrochemical products and organic materials. Among many known
heterocyclic moieties, quinoline and its derivatives are one of the privileged scaffolds found in many
natural products. In general, quinoline derivatives could be prepared by utilizing ortho-substituted
anilines and carbonyl compounds containing a reactive α-methylene group of well-known reaction
routes like Friedlander synthesis, Niemantowski synthesis and Pfitzinger synthesis. Moreover,
polysubstituted quinolones and their derivatives also had shown considerable interest in the fields of
organic and pharmaceutical chemistry in recent years.
Objective:
The main objective of our research work is towards the design and synthesis of
divergent biological-oriented, proactive analogues with potential pharmacological value inspired by
the anti-tubercular activity of 2-phenylquinoline analogues. In this study, we have been interested in
the design and synthesis of bioactive, 2, 4-diphenyl, 8-arylated quinoline analogues.
Methods:
6-phenyl-6h-chromeno [4, 3-b] quinoline derivatives were synthesized from 4-chloro-2-
phenyl-2H-chromene-3-carbaldehyde and various substituted aromatic anilines as starting materials
using sodium bisulfate embedded SiO2 re-usable catalyst. All these fifteen new compound structures
confirmed by spectral data 1H & 13C NMR, Mass, CHN analysis etc. Furthermore, all these new
compounds antibacterial activity strains recorded using the paper disc method. The compound
molecular structures were designed using molecular docking study by utilizing the crystallographic
parameters of S. Areus Murb protein.
Results:
A series of fifteen new quinoline derivatives synthesized in moderate to good yields using
sodium bisulfate embedded SiO2 re-usable catalyst. The molecular structures of these newly
synthesized compounds elucidated by the combination of spectral data along with the elemental
analysis. These compounds antibacterial activity study have shown moderate to good activity against,
Escherichia coli (Gram-negative) and Staphylococcus aureus (gram-positive) organisms. These
antibacterial activity results were also a very good correlation with molecular docking studies.
Conclusion:
In this study, fifteen new quinoline derivatives synthesized and structures confirmed by
spectral data. In fact, all the compounds have shown moderate to good antibacterial activity. In
general, the compounds containing the electron donor group at R1 position (R1 = OMe) and the
acceptor group at R2 positions (R2 = F or Cl) had shown good antibacterial activity. These antibacterial
activity results were also a very good correlation with molecular docking studies showing strong
binding energies with the highest value being, -12.45 Kcal mol-1 with S. aureus MurB receptor.

Abstract
BACKGROUND Breast Cancer (BC) is the second most common cause of cancer related deaths in women. Due to severe side effects and multidrug resistance, current therapies like hormonal therapy, surgery, radiotherapy and chemotherapy become ineffective. Also, the existing drugs for BC treatment are associated with several drawbacks such as poor oral bioavailability, non-selectivity and poor pharmacodynamics properties. Therefore, there is an urgent need for the development of more effective and safer anti BC agents. OBJECTIVE This article explored in detail the possibilities of indole-based heterocyclic compounds as anticancer agents with breast cancer as their major target. METHODS Recent literature related to indole derivatives endowed with encouraging anti BC potential is reviewed. With special focus on BC, this review offers a detailed account of multiple mechanisms of action of various indole derivatives: aromatase inhibitor, tubulin inhibitor, microtubule inhibitor, targeting estrogen receptor, DNA-binding mechanism, induction of apoptosis, inhibition of PI3K/AkT/NFkB/mTOR, and HDAC inhibitors, by which these derivatives have shown promising anticancer potential. RESULTS Exhaustive literature survey indicated that indole derivatives are associated with properties of inducing apoptosis and disturbing tubulin assembly. Indoles are also associated with the inhibition of NFkB/mTOR/PI3K/AkT and regulation of estrogen-mediated activity. Furthermore, indole derivatives have been found to modulate critical targets such as topoisomerase and HDAC. These derivatives have shown significant activity against breast cancer cells. CONCLUSION In BC, indole derivatives seem to be quite competent and act through various mechanisms that are well established in case of BC. This review has shown that indole derivatives can further be explored for the betterment of BC chemotherapy. A lot of potential is still hidden which demands to be discovered for upgrading BC chemotherapy.

Abstract
Carbazole is an important type of tricyclic nitrogen containing compound and isolated first from coal tar in 1872 by Graebe and Glazer. Carbazole alkaloids have received considerable attention since their discovery in the 1960’s and their derivatives are well known for their pharmacological activities. Many recent studies have reported that carbazole derivatives exhibit a variety of biological activities. Toxicity of test compound in cells was determined by MTT assay based on mitochondrial reduction of yellow MTT tetrazolium dye to a highly blue colored formazan product. Among the ten synthesized compounds, 12c, 12d, 12e, 12f, 12g and 12i were showed good activity. In which 12c, 12d and 12e showed moderate activity on MCF-7 cancer cell line. Compounds 12f, 12g and 12i showed more potent activity than control. Compounds 12f, 12g and 12i showed more potent activity than control adriamycin. In future, we will plan further mechanistic studies on most potent active compounds 12f, 12g and 12i.

Abstract
In recent years, indole-indazolyl hydrazide-hydrazone derivatives with strong cell growth inhibition and apoptosis induction characteristics are being strongly screened for their cancer chemo-preventive potential. In the present study, N-methyl and N,N-dimethyl bis(indolyl)hydrazide-hydrazone analog derivatives were designed, synthesized and allowed to evaluate for their anti-proliferative and apoptosis induction potential against cervical (HeLa), breast (MCF-7 and MDA-MB-231) and lung (A549) cancer cell lines relative to normal HEK293 cells. The MTT assay in conjunction with mitochondrial potential assays and the trypan blue dye exclusion were employed to ascertain the effects of the derivatives on the cancer cells. Further, mechanistic studies were conducted on compound 14a to understand the biochemical mechanisms and functional interactions with various signaling pathways triggered in HeLa and MCF-7 cells. Compound 14a induced apoptosis via caspase independent pathway through the participation of mitogen-activated protein kinases (MAPK) such as extracellular signal related kinase (ERK) and p38 as well as p53 pathways. It originates the activation of pro-apoptotic proteins such as Bak and Mcl-1s and also strongly induced the generation of reactive oxygen species. In downstream signaling pathway, activated p53 protein interacted with MAPK pathways, including SAPK/c-Jun N-terminal protein kinase (JNK), p38 and ERK kinases resulting in apoptotic cell death. The involvement of MAPK cascades such as p38, ERK and p38 on compound 14a induced apoptotic cell death was evidenced by the fact that the inclusion of specific inhibitors of p38, ERK1/2 and JNK MAPK (SB2035809, PD98059 and SP600125) prevented the compound 14a towards induced apoptosis. The results clearly showed that MAP kinase cascades were crucial for apoptotic response in compound 14a induced cellular killing and were dependent on p53 activity. Based on the results, compound 14a was identified as a promising candidate for cancer therapeutics and these findings furnish a basis for further in vivo experiments on anti-proliferative activity.
