Abstract
Thiazolo[4,5-d]pyrimidine is one of the purine isosteres that possesses a variety of pharmaceutical activities and is an attractive scaffold for drug discovery. In this work, a novel protocol for the synthesis of 7-aminothiazolo[4,5,-d]pyrimidine scaffold libraries on solid support has been developed using a traceless linker. Dimroth rearrangement afforded the desired intermediate with a fused heterocyclic thiazolo[4,5,-d]pyrimidine core skeleton. To diversify the synthesized library, three types of building blocks were introduced to the resin-bound thiazolo[4,5,-d]pyrimidine through N-acylation, N-alkylation, and nucleophilic substitution with amines during cleavage from the resin. The synthesized compounds were produced in seven steps with overall yields of 11-48%. Additionally, physicochemical properties, as well as drug-likeness of the library, were calculated.

Abstract
The present study describes the synthesis of three series of 4-substituted pyridopyrimidin derivatives 4a-h, 5a-d. 6a-d, starting from 2-amino-6-(4-methoxyphenyl)-4-(4-(substituted) phenyl)nicotinonitrile 2a-d via the reaction with N,N-dimethyl-N-' substituted phenyl formimidamide to obtain 4a-h or with either phenyl isothiocyanate 1:1 and 1:2 to obtain 5a-d, 6a-d respectively. The synthesized compounds were evaluated for their effectiveness as EGFR inhibitors against Gefitinib. Six compounds; 4b,g,h, 5c and 6a,d prompted significantly higher EGFR inhibitory activity relative to that of Gefitinib. While two compounds 4d and 4f showed IC50 values non-significantly different from that of the reference drug. Furthermore, compounds 4a, 4 h, 6a and 6d were chosen to be assessed in vitro for their cytotoxicity against two EGFR-overexpressing cell lines; two human cancer cell lines namely: MCF7 and MDA-MB-361. Moreover, cell cycle analysis and apoptotic assay was applied for compound 4b that showed most potent inhibitory activity on EGFR, and the highest cytotoxicity against MCF7 and MDA-MB-361, where cell cycle arrest was achieved at pre G and S phases with increased apoptosis. Additionally, a molecular docking study was achieved to inspect the interaction of this compound with the active site of EGFR-TK.

Abstract
In the Dimroth rearrangement of heterocycles, often pyrimidines, an exocyclic and a ring substituent are interchanged. However, the term Dimroth rearrangement is frequently used even when there is no knowledge of the reaction mechanism and alternatives are likely. Here, we have employed density functional theory (DFT) calculations at the M06-2X/6-311+G(d,p) level to determine the most plausible rearrangement pathways of 3-aminothiocarbonylquinazoline 5, tetrahydrofuranylpyrimidine 21, and 5-allyltriazocine 30. For the rearrangement of quinazoline 5 to 9, the [1,3]-sigmatropic shift of the thioamido group with an activation barrier of 26.7 kcal/mol is much preferred over the Dimroth rearrangement (∼46 kcal/mol). An even lower barrier of 21.6 kcal/mol applies to a stepwise [1,3]-shift. The migration of the tetrahydrofuranyl unit in pyrimidines like 21 → 23 can take place by means of a [1,3]-sigmatropic shift with a low barrier (≤17.5 kcal/mol) rather than a Dimroth rearrangement under acidic conditions and most likely also under neutral conditions (∼30 kcal/mol). In the rearrangement of 5-allyl-6-iminotriazocine 30 to 32, the [3,3]-sigmatropic shift (aza-Cope rearrangement) is preferred over the Dimroth mechanism under neutral conditions, but in the presence of acid, the azonia-Cope rearrangement of an allyl group and the true Dimroth rearrangement have comparable activation energies.

Abstract
This paper reports a convenient sequential one-pot approach for the synthesis of an array of 14 pyrazolo[1,5-a][1,3,5]triazines, substituted in C8 by halogen (Br), various functions (CN and CO2Et) and alkyl or (het)aryl groups. This study confirms the interest of combining the efficient heating obtained under dielectric microwave heating and the achievement of sequential one-pot reactions, avoiding the tedious work-up and purification of intermediate compounds, achieving sustainable synthesis processes. Considering usual conventional methods, this microwave protocol is featured by advantages in terms of yields, reaction times, and convenient gram scale synthesis.

Abstract
HER2 kinase as a well-established target for breast cancer (BC) therapy is associated with aggressive clinical outcomes; thus, herein we present structural optimization for HER2-selective targeting. HER2 profiling of the developed derivatives demonstrated potent and selective inhibitions (IC50: 5.4-12 nM) compared to lapatinib (IC50: 95.5 nM). Favorably, 17d exhibited minimum off-target kinase activation. NCI-5-dose screening revealed broad-spectrum activities (GI50: 1.43-2.09 μM) and 17d had a remarkable selectivity toward BC. Our compounds revealed significant selective and potent antiproliferative activities (∼20-fold) against HER2+ (AU565, BT474) compared to HER2(-) cells. At 0.1 IC50, 15i, 17d, and 25b inhibited pERK1/2 and pAkt by immunoblotting. Furthermore, 17d demonstrated potent in vivo tumor regression against the BT474 xenograft model. Notably, a metastasis case was observed in the vehicle but not in the test mice groups. CD-1 mice metabolic stability assay revealed high stability and low intrinsic clearance of 17d (T1/2 > 145 min and CLint(mic) < 9.6 mL/min/kg).

Abstract
Molecular rearrangements are important tools to increase the molecular diversity
of new bioactive compounds, especially in the class of heterocycles. This review deals
specifically with a very famous and widely applicable rearrangement known as the Dimroth
Rearrangement. Although it has originally been observed for 1,2,3-triazoles, its amplitude
was greatly expanded to other heterocycles, as well as from laboratory to large
scale production of drugs and intermediates. The reactions that were discussed in this review
were selected with the aim of demonstrating the windows that may be open by the
Dimroth's rearrangement, especially in what regards the development of new synthetic approaches
toward biologically active compounds.

Abstract
Efficient microwave-assisted chemical processes were applied to the synthesis of an array of novel N-(4-methoxyphenylamino)-2-methyl benzo-, pyrido- or pyrazino-thieno[3,2-d]pyrimidin-4-amine derivatives. These heteroaromatic systems were envisioned as potent bioisosteric analogues of MPC-6827, an anticancer agent previously developed until phase II clinical studies. A brief evaluation and comparison of their antiproliferative activity on HT-29 and Caco-2, two human colorectal cancer cell lines, were also reported. At the tested concentrations (5 and 10 µM), thieno[3,2-d]pyrimidin-4-amines 4a and 4c exhibited an inhibitory effect similar to MPC-6827 on human colorectal cancer cell proliferation.

Abstract
We previously highlighted the interest in 6,5,6-fused tricyclic analogues of 4-aminoquinazolines as kinase inhibitors in the micromolar to the nanomolar range of IC50 values. For the generation of chemical libraries, the formamide-mediated cyclization of the cyanoamidine precursors was carried out under microwave irradiation in an eco-friendly approach. In order to explore more in-depth the pharmacological interest in such tricyclic skeletons, the central five member ring, i.e., thiophène or furan, was replaced by a pyrrole to afford 9H-pyrimido[5,4-b]- and [4,5-b]indol-4-amine derivatives inspired from harmine. The inhibitory potency of the final products was determined against four protein kinases (CDK5/p25, CK1δ/ε, GSK3α/β, and DYRK1A). As a result, we have identified promising compounds targeting CK1δ/ε and DYRK1A and displaying micromolar and submicromolar IC50 values.

Herein, we sought to design, synthesize, and evaluate a novel 4-anilinoquinazoline derivative and identify its anti-tumor activity in vitro and in vivo. The novel compound, N-(4-methoxyphenyl)-N-methyl-2-(methyl-d3)quinazolin-4-amine (AQ-4), was identified as a representative scaffold and potent microtubule-targeting agent. As a promising antimitotic agent, AQ-4 displayed remarkable anti-tumor activity with an average IC50 value of 19 nM across a panel of 14 human cancer cell lines. AQ-4 also exhibited nearly identical potent activities against drug-resistant cells, with no evidence of toxicity towards normal cells. A further target verification study revealed that AQ-4 targets the tubulin-microtubule system by significantly inhibiting tubulin polymerization and disrupting the intracellular microtubule spindle dynamics. According to the results of mechanism study, AQ-4 induced cell cycle arrest in the G2/M phase, promoting evident apoptosis and a collapses of mitochondrial membrane potential. The superior anti-tumor effect of AQ-4 in vivo suggests that it should be further investigated to validate its use for cancer therapy.

Abstract
Efficient metal catalyzed C⁻H arylation of 8-alkyl-thiazolo[5,4-f]-quinazolin-9-ones was explored for SAR studies. Application of this powerful chemical tool at the last stage of the synthesis of kinase inhibitors allowed the synthesis of arrays of molecules inspired by fragment-growing studies generated by molecular modeling calculations. Among the potentially active compounds designed through this strategy, FC162 (4c) exhibits nanomolar IC50 values against some kinases, and is the best candidate for the development as a DYRK kinase inhibitor.

Abstract
Vandetanib is an orally available tyrosine kinase inhibitor used in the treatment of cancer. The current synthesis proceeds via an unstable 4-chloroquinazoline, using harsh reagents, in addition to requiring sequential protection and deprotection steps. In the present work, use of the Dimroth rearrangement in the key quinazoline forming step enabled the synthesis of Vandetanib in nine steps (compared to the previously reported 12-14).

Abstract
A library of thirty novel thiazolo[5,4-f]quinazolin-9(8H)-one derivatives belonging to four series designated as 12, 13, 14 and 15 was efficiently prepared, helped by microwave-assisted technology when required. The efficient multistep synthesis of methyl 6-amino-2-cyano- benzo[d]thiazole-7-carboxylate (1) has been reinvestigated and performed on a multigram scale. The inhibitory potency of the final products against five kinases involved in Alzheimer's disease was evaluated. This study demonstrates that some molecules of the 12 and 13 series described in this paper are particularly promising for the development of new multi-target inhibitors of kinases.

Abstract
This paper reports the design and synthesis of a novel series of 8-arylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4-amines via microwave-assisted multi-step synthesis. A common precursor of the whole series, 3-amino-5-bromothieno[2,3-b]pyridine-2-carbonitrile, was rapidly synthesized in one step from commercially-available 5-bromo-2-chloronicotinonitrile. Formylation with DMF-DMA led to (E)-N'-(5-bromo-2-cyanothieno[2,3-b]pyridin-3-yl)-N,N-dimethylformimidamide (4) which was conveniently functionalized at position 8 by palladium-catalyzed Suzuki-Miyaura cross-coupling to introduce a heteroaromatic ring. High-temperature formamide-mediated cyclization of the cyanoamidine intermediate gave seventeen 8-arylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4-amines. The inhibitory potency of the final products was evaluated against five protein kinases (CDK5/p25, CK1δ/ε, GSK3α/β, DYRK1A and CLK1) and revealed that 8-(2,4-dichlorophenyl)pyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4-amine 1g specifically inhibits CK1δ/ε and CLK1 (220 and 88 nM, respectively) while its 7-(2,4-dichlorophenyl)pyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4-amine isomer 10 showed no activity on the panel of tested kinases. Molecular modelling of 10 and 1g in the ATP binding sites of CK1δ/ε and CLK1 showed that functionalization at position 7 of pyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4-amines is likely to induce a steric clash on the CK1δ/ε P-loop and thus a complete loss of inhibitory activity.

Abstract
Quinazoline has been reported to exhibit multiple bioactivities. The aim of this study was to discover new quinazoline derivatives with preventive effect on lipopolysaccharide-induced acute lung injury via anti-inflammatory actions. Thirty-three 4-amino quinazolin derivatives were synthesized and screened for anti-inflammatory activities in lipopolysaccharide-induced macrophages. The most potent four compounds, 6h, 6m, 6p, and 6q, were shown dose-dependent inhibition against lipopolysaccharide-induced TNF-α and IL-6 release. Then, the preliminary structure-activity relationship and quantitative structure-activity relationship analyses were conducted. To further determine the effects of quinazolines on acute lung injury treatment, lipopolysaccharide-induced acute lung injury model was employed. Male Sprague Dawley rats were pretreated with 6m or 6q before instillation of lipopolysaccharide. The results showed that 6m and 6q, especially 6q, obviously alleviated lung histopathological changes, inflammatory cells infiltration, and cytokines mRNA expression initiated by lipopolysaccharide. Taken together, this work suggests that 6m and 6q suppressed the lipopolysaccharide-induced acute lung injury through inhibition of the inflammatory response in vivo and in vitro, indicating that quinazolines might serve as potential agents for the treatment of acute lung injury and deserve the continuing drug development and research.

Abstract
The convenient synthesis of a library of novel 6,6,5-tricyclic thiazolo[5,4-f] quinazolines (forty molecules) was achieved mainly under microwave irradiation. Dimroth rearrangement and 4,5-dichloro-1,2,3,-dithiazolium chloride (Appel salt) chemistry were associated for the synthesis of a novel 6-aminobenzo[d]thiazole-2,7-dicarbonitrile (16) a versatile molecular platform for the synthesis of various bioactive derivatives. Kinase inhibition of the final compounds was evaluated on a panel of four Ser/Thr kinases (DYRK1A, CDK5, CK1 and GSK3) chosen for their strong implications in various regulation processes, especially Alzheimer's disease (AD). In view of the results of this preliminary screening, thiazolo[5,4-f]quinazoline scaffolds constitutes a promising source of inspiration for the synthesis of novel bioactive molecules. Among the compounds of this novel chemolibrary, 7i, 8i and 9i inhibited DYRK1A with IC50 values ranging in the double-digit nanomolar range (40, 47 and 50 nM, respectively).

Abstract
The convenient synthesis of a focused library (forty molecules) of novel 6,6,5-tricyclic thiazolo[5,4-f]quinazolines was realized mainly under microwave irradiation. A novel 6-aminobenzo[d]thiazole-2,7-dicarbonitrile (1) was used as a versatile molecular platform for the synthesis of various derivatives. Kinase inhibition, of the obtained final compounds, was evaluated on a panel of two kinases (DYRK1A/1B) together with some known reference DYRK1A and DYRK1B inhibitors (harmine, TG003, NCGC-00189310 and leucettine L41). Compound IC50 values were obtained and compared. Five of the novel thiazolo[5,4-f]quinazoline derivatives prepared, EHT 5372 (8c), EHT 6840 (8h), EHT 1610 (8i), EHT 9851 (8k) and EHT 3356 (9b) displayed single-digit nanomolar or subnanomolar IC50 values and are among the most potent DYRK1A/1B inhibitors disclosed to date. DYRK1A/1B kinases are known to be involved in the regulation of various molecular pathways associated with oncology, neurodegenerative diseases (such as Alzheimer disease, AD, or other tauopathies), genetic diseases (such as Down Syndrome, DS), as well as diseases involved in abnormal pre-mRNA splicing. The compounds described in this communication constitute a highly potent set of novel molecular probes to evaluate the biology/pharmacology of DYR1A/1B in such diseases.

Abstract
The efficient synthesis of 7-substituted pyrido[2',3':4,5]furo[3,2-d]pyrimidin-4-amines and their N-aryl analogues is described. 3,5-Dibromopyridine was converted into 3-amino-6-bromofuro[3,2-b]pyridine-2-carbonitrile intermediate which was formylated with DMFDMA. Functionalization at position 7 of the tricyclic scaffold was accomplished, before or after cyclisation step, by palladium-catalyzed Suzuki-Miyaura cross-coupling while the pyrimidin-4-amines and N-aryl counterparts were synthesized by microwave-assisted formamide degradation and Dimroth rearrangement, respectively. The final products were evaluated for their potent inhibition of a series of five Ser/Thr kinases (CDK5/p25, CK1δ/ε, CLK1, DYRK1A, GSK3α/β). Compound 35 showed the best inhibitory activity with an IC50 value of 49 nM and proved to be specific to CLK1 among the panel of tested kinases.

Abstract
Novel N-aryl-7-methoxybenzo[b]furo[3,2-d]pyrimidin-4-amines (1) and their N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amine analogues (2) were designed and prepared for the first time via microwave-accelerated multi-step synthesis. Various anilines were condensed with N'-(2-cyanaryl)-N,N-dimethylformimidamide intermediates obtained by reaction of 3-amino-6-methoxybenzofuran-2-carbonitrile (3) and 3-amino-6-methoxybenzothiophene-2-carbonitrile (4) precursors with dimethylformamide dimethylacetal. The inhibitory potency of the final products against five protein kinases (CDK5/p25, CK1δ/ε, GSK3α/β, DYRK1A and CLK1) was estimated. Compounds (2a-z) turned out to be particularly promising for the development of new pharmacological dual inhibitors of CLK1 and DYRK1A kinases.
