Abstract
Cancer is one of the leading causes of death. Globally a huge number of deaths and new incidences are reported annually. Heterocyclic compounds have been proved to be very effective in the treatment of different types of cancer. Among different heterocyclic scaffolds, quinazoline and quinazolinone core were found versatile and interesting with many biological activities. In the discovery of novel anticancer agents, the Quinazoline core is very effective. The FDA has approved more than 20 drugs as an anticancer bearing quinazoline or quinazolinone core in the last two decades. One prime example is Dacomitinib, which was newly approved for non-small-cell lung carcinoma treatment in 2018. These drugs work by different pathways to prevent the spread of cancer cell progression, including inhibition of different kinases, tubulin, kinesin spindle protein, and so forth. This review presented recent developments of quinazoline/quinazolinone scaffold bearing derivatives as anticancer agents acting as epidermal growth factor receptor (EGFR) vascular endothelial growth factor receptor (VEGFR), and dual EGFR/VEGFR inhibitors.

Abstract
INTRODUCTION Hyperactivated RAS signaling is reported in 13% of all human cancers, in which ~80% resulted due to KRAS mutations alone. Direct inhibition of KRAS is an important aspect in treating KRAS-related tumors. Despite the efforts of more than four decades, not many KRAS inhibitors have been successful in obtaining clinical approval, except the very recent FDA approval for sotorasib. In recent years, the understanding of structural insights and allosteric pocket identification at catalytic sites of KRAS are likely to provide an excellent opportunity for the development of much more effective clinical candidates. AREA COVERED The presented review article mainly summarizes the developments of small molecule KRAS inhibitors as drug candidates and rational approaches that are being utilized for the selective targeting of KRAS signaling in the mutant cancer cells. EXPERT OPINION After the initial success in targeting the mutant KRAS G12C variants, the search has been shifted to address the challenges concerning the resistance and efficacy of small molecule KRAS inhibitors. However, the contribution of other KRAS mutations at G12V, G13C, and G13D variants causing cancers is much higher than the mutations at G12C. In view of this aspect, specific attention is required to target all other mutations as well. Accordingly, for the development of KRAS targeted therapies, the design of small molecule inhibitors that can inhibit KRAS signaling and as well as target inhibition of other signaling pathways like RAS-SOS and RAS-PI3K has to be explored extensively.

Abstract
Dual TK inhibitors have shown significant clinical effects against many tumors, but with unmanageable side effects. Design approach and selectivity of these inhibitors plays substantial role in their potency and side-effects. Understanding the homology of binding sites in targeted receptors, and involvement of signaling proteins after the inhibition might help in producing less toxic but effective inhibitors. Herein, we designed benzylideneindolon-2-one derivatives based on homology modeling in binding sites of VEGFR-2 and EGFR receptors as dual- inhibitor potent anticancer compounds with high selectivity. The benzylideneindolon-2-one derivatives were found to possess conformational switch in form of oxindole, substituted at 2-benzimidazole. Within synthesized compounds, 5b was found most active in in-vitro enzyme inhibition assay against VEGFR-2 and EGFR with highest IC50 value of 6.81 ± 2.55 and 13.04 ± 4.07 nM, respectively. Interestingly, cytotoxicity studies revealed selective toxicity of compound 5b against proliferation of A-431 cell lines (over expressed VEGFR-2 and EGFR) with GI50 value of 0.9 ± 0.66 µM. However, the compounds showed mild to moderate activity in all other cancer cell line in the range of 0.2-100 μM. Further mode of action studies by flow cytometry and western blot on A-431 indicated that they work via apoptosis at S- phase following Bcl/Bax pathway, and cell migration via MMP9. 5b not only suppressed tumor growth but also improved vandetanib associated with weight loss toxicity. Moreover, 5b was found safer than sunitinib and erlotinib with LD50 of 500 mg/kg body weight. These results propose 5b as potential anti-tumor drug with safer profile of conventional inhibitors of VEGFR-2 and EGFR for solid tumors.

Abstract
The research presented aims at developing Ropinirole hydrochloride (RHCl) nanoemulsion (NE) with nigella oil for Parkinson's disease (PD). In silico study was done to explore interactions of ropinirole and thymoquinone at receptor site (TNF-α and NFK-β). Ropinirole and Thymoquinone forms a hydrogen bond with residue Arginine 201 and residue Arginine 253 with a bond length of 1.89 Å and 2.30 Å at the NF-κβ receptor. NE was optimized using Central Composite Rotatable Design (CCRD). The globule size of chitosan coated NE, Polydispersity index (PDI) and zeta potential were 183.7 ± 5.2 nm, 0.263 ± 0.005, and 24.9 mV respectively. NE exhibited 85.28% transmittance showing the formulation was clear and transparent. TEM showed that NE had spherical globules with no aggregation. The formulation had a stable pH value of 5.8 ± 0.18. In vitro release and permeation studies exhibited 2 folds and 3.4 folds enhancement when compared with the drug suspension. Neurobehavioral activity and biochemical parameters corroborated well with the pharmacokinetic results. Histopathological study and immunohistochemical analysis were performed to get better picture of 6-OHDA induced toxicity and reversal of PD symptoms. Thus, the NE tailored is a promising synergistic approach yielding enticing outcomes for better management of PD related symptoms.

Abstract
In the present scenario, there has been a lot of consideration toward the field of free radical chemistry. Free radicals responsive oxygen species are produced by different endogenous frameworks, exposure to various physicochemical conditions, radiation, toxins, metabolized drug by-product, and pathological states. On the off chance that free radical overpowers the body's capacity, it generates a condition known as oxidative stress, which can alter physiological conditions of the body and results in several diseases. For appropriate physiological function, it is necessary to have a proper balance between free radicals and antioxidants. Antioxidants chemically inhibit the oxidation process; they are also known as free radical scavengers. For tackling the problem of oxidative stress application of an external source of antioxidant is helpful. A lot of antioxidants of natural, semi-synthetic and synthetic origin are in use, with time search of more effective, nontoxic, safe antioxidant is intensified. The present review, discuss different synthetic derivatives bearing various heterocyclic scaffolds as radical scavengers.

Abstract
INTRODUCTION A novel anticancer therapy is the need of the hour due to growing incidences of resistance to first line cancer chemotherapy. Synthetic lethality (SL) is one of the new age treatment methods being explored for combating the resistance to anticancer agents. In this method, cell mutations are exploited for the development of new therapeutic agents, where, if there is loss of function of one gene, the cell mutations can still be fixed by alternative machinery but if two genes involved in DNA repair undergo loss of function, it causes lethality to the cell. AREAS COVERED The authors condense findings of SL-based novel anticancer regimen. The review emphasizes some of the SL based clinical and preclinical studies of novel targets and therapy. EXPERT OPINION SL conceptualizes a resolution against treatment resistance to anticancer regimen by recognition of therapeutic vulnerabilities in particular cancer cells. A multitude of clinical trials associated with SL and DNA repair are being conducted that will be useful in obtaining a clearer picture pertaining to the use of cancer biomarkers and effectiveness of drugs acting via target-based molecular changes. Furthermore, new anticancer regimen focused on personalized medicines will emerge basing their development upon SL.

Abstract
A set of two series of 1,3,4-oxadiazole (11a-n) and 1,2,4-Triazole (12a, c, e, g, h, j-n) based topsentin analogues were prepared by replacing imizadole moiety of topsentin through a multistep synthesis starting from indole. All the compounds synthesized were submitted for single dose (10 µM) screening against a NCI panel of 60-human cancer cell lines. Among all cancer cell lines, colon (HCC-2998) and Breast (MCF-7, T-47D) cancer cell lines were found to be more susceptible for this class of compounds. Among the compounds tested, compounds 11a, 11d, 11f, 12e and 12h, were exhibited good anti-proliferative activity against various cancer cell lines. Compounds 11d, 12e and 12h demonstrated better activity with IC50 2.42 µM, 3.06 µM, and 3.30 µM respectively against MCF-7 human cancer cell line than that of the standard drug doxorubicin IC50 6.31 µM. Furthermore, 11d induced cell cycle arrest at G0/G1 phase and also disrupted mitochondrial membrane potential with reducing cell migration potential of MCF-7 cells in dose dependent manner. In vitro microtubule polymerization assays found that compound 11d disrupt tubulin dynamics by inhibiting tubulin polymerization with IC50 3.89 μM compared with standard nocodazole (IC50 2.49 μM). In silico docking studies represented that 11d was binding at colchicine binding site of β-tubulin. Compound 11d emerged as lead molecule from the library of compounds tested and this may serve as a template for further drug discovery.

Abstract
Alzheimer, the fourth leading cause of death embodies a key responsible event including formation of β-amyloid protein clustering to amyloid plaque on blood vessels. The origin of above events is Amyloid precursor protein (APP) which is an integral membrane protein known for its function in synapses formation. Modern research had proposed that the over expression of DYRK1A (Dual specificity tyrosine phosphorylation regulated kinase1A, a family of protein kinases, positioned within the Down's syndrome critical region (DSCR) on human chromosome 21causes phosphorylation of APP protein resulting in its cleavage to Aβ 40, 42 and tau proteins (regulated by beta and gamma secretase) which plays critical role in early onset of Alzheimer's disease (AD) detected in Down's syndrome (DS), leading to permanent functional and structural deformities which results ultimately into neuro-degeneration and neuronal death. Therefore, DYRK1A emerges as a potential target for prevention of neuro-degeneration and hence Alzheimer. Presently, the treatment methods for Down's syndrome, as well as Alzheimer's disease are extremely biased and represent a major deficiency for therapeutic necessities. We hereby, focus our review on the current status of the research and contributions in the development of DYRK1A inhibitors.

Abstract
A new series of benzimidazole linked pyrazole derivatives were synthesized by cyclocondensation reaction through one-pot multicomponent reaction in absolute ethanol. All the synthesized compounds were tested for their in vitro anticancer activities on five human cancer cell lines including MCF-7, HaCaT, MDA-MB231, A549 and HepG2. EGFR receptor inhibitory activities were carried out for all the compounds. Majority of the compounds showed potent antiproliferative activity against the tested cancer cell lines. Compound 5a showed the most effective activity against the lungs cancer cell lines (IC50 = 2.2 µM) and EGFR binding (IC50 = 0.97 µM) affinity as compared to other members of the series. Compound 5a inhibited growth of A549 cancer cells by inducing a strong G2/M phase arrest. In addition, same compound inhibited growth of A549 cancer cells by inducing apoptosis. In molecular docking studies compound 5a was bound to the active pocket of the EGFR (PDB 1M17) with five key hydrogen bonds and two π-π interaction with binding energies ΔG = -34.581 Kcal/mol.

Abstract
OBJECTIVE The present review article presented a detailed account of the design strategies and the structure activity relationship of different derivatives apart from the nitrogen containing ring. These scaffolds play an important part in the drug discovery which showed anticancer activity against different human cancer cell lines through apoptosis, cell cycle arrest, inhibiting kinases, angiogenesis, disruption of cell migration, modulation of nuclear receptor responsiveness and others. Naphthalenes amides/amidines, furan, podophyllotoxin, platinum compounds, steroids, and urea, which forms the core part or along with other N-heterocyclic rings are enclosed. Some of these compounds e.g. podophyllotoxin and platinum based drugs displayed anticancer activity at nanomolar range. Various substitutions from the earlier and latest information are prerequisite in the drug synthesis process. CONCLUSION The review focused on the recent development of these derivatives, design and anticancer properties, thus providing with the most profound knowledge for the development of targeted based anticancer drugs.

Abstract
In this paper, we report the synthesis of 2-[(6-substituted benzo[d]thiazol-2-ylcarbamoyl)methyl]-1-(4-substituted phenyl)isothiourea derivatives (4a-y) carrying active pharmacophores essential for anticonvulsant activity. The anticonvulsant activity was evaluated in vivo by maximal electroshock (MES) test and subcutaneous pentylenetetrazole (scPTZ) test in mice. Most of the compounds showed promising anticonvulsant activity. The most active compounds 4b and 4q were found active in both MES and scPTZ models, without signs of neurotoxicity. Compound 4b showed the moderate change in SGOT and alkaline phosphatase level as compared to control. Compounds 4b and 4w were also found to elevate GABA levels in the olfactory lobe, mid brain, medulla oblongata and cerebellum regions of rat brain. In molecular docking study, the title compounds exhibited good binding properties with epilepsy molecular targets such as GABA-A. Structure-activity relationships are also elaborated along with the analysis of lipophilicity. The results suggested that compound 4b is likely to have varied mechanisms of action including voltage-gated ion channel inhibition and modulating GABAergic action.

Abstract
The present review article offers a detailed account of the design strategies employed for the synthesis of nitrogen-containing anticancer agents. The results of different studies describe the N-heterocyclic ring system is a core structure in many synthetic compounds exhibiting a broad range of biological activities. Benzimidazole, benzothiazole, indole, acridine, oxadiazole, imidazole, isoxazole, pyrazole, triazoles, quinolines and quinazolines including others drugs containing pyridazine, pyridine and pyrimidines are covered. The following studies of these compounds suggested that these compounds showed their antitumor activities through multiple mechanisms including inhibiting protein kinase (CDK, MK-2, PLK1, kinesin-like protein Eg5 and IKK), topoisomerase I and II, microtubule inhibition, and many others. Our concise representation exploits the design and anticancer potency of these compounds. The direct comparison of anticancer activities with the standard enables a systematic analysis of the structure-activity relationship among the series.

Abstract
In present investigation a series of 28 oxadiazole analogues (AB1-AB28) were subjected to molecular properties prediction, drug-likeness by Molinspiration (Molinspiration, 2008) & MolSoft (MolSoft, 2007) softwares, lipophilicity and solubility parameters using ALOGPS 2.1 program. Out of 28 analogues only 16 were chosen on the basis of Lipinski "Rule of Five" (Ro5) for the synthesis and antimicrobial screening as oral bioavailable drugs/leads. Maximum drug-likeness model score (1.22) was found to be of compound AB13. Selected compounds (AB1-AB2), (AB5-AB9), (AB12-AB16), (AB18-AB21) were synthesized and characterized by IR, NMR and mass spectral analysis followed by antibacterial and antifungal screening. It was observed that compounds showed moderate to good antibacterial activity, but their antifungal activity was somewhat moderate. Compounds AB13 and AB20 showed pronounced activity against all bacterial and fungal strains. We had noticed that compounds (AB13, AB20) bearing OH group at one of the phenyl ring of oxadiazole exhibited good antimicrobial properties and their drug-likeness model score were also predicted maximum among the series.

Abstract
Most reports of patients with primary small bowel volvulus have indicated that the ingestion of a high-bulk vegetable diet in some way contributes to the development of this condition. During a recent 13-month period at Nangarhar University Hospital at Jalalabad, Afghanistan, the frequency of occurrence among 26 patients was found to be related to abrupt changes in dietary intake. The first and last months of the study were Ramadan, the annual period in which Mohammedans abstain from all oral intake during daylight hours and take a single large meal after dark. During these two isolated months, there was a ten fold and nine fold increase, respectively, in the incidence of the condition. Early diagnosis and surgical intervention offer the only possibility for minimizing an otherwise excessive mortality.
