Check Digit Verification of cas no

The CAS Registry Mumber 1608-51-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1608-51:
(6*1)+(5*6)+(4*0)+(3*8)+(2*5)+(1*1)=71
71 % 10 = 1
So 1608-51-1 is a valid CAS Registry Number.

Molecular recognition of synthesized halogenated chalcone by calf thymus DNA through multispectroscopic studies and analysis the anti-cancer, anti-bacterial activity of the compounds

Ghosh, Sudipta,Ghosh, Suvranil,Mahato, Sachinta,Majee, Adinath,Mukherjee, Abhijit,Pal, Mahadeb,Sen, Sukanta Kumar,Singh, Bula

, (2021)

The present study aims to elucidate the anti-cancer, antimicrobial activity of synthesized halogenated chalcones (1f, 1h, 1i) and their molecular interaction with calf thymus DNA. All the three compounds were characterized using different spectroscopic tools like FTIR, NMR. DFT and TDDFT computation were performed to support the structural and electronic parameter of the compounds. UV–vis absorbance, steady-state fluorescence, time-resolved fluorescence, circular dichroism, helix melting, molecular docking study reveals that the compounds (1f, 1h, 1i) actively interact with ctDNA via groove binding mode. The binding constants (Kb) were calculated to be 1.29 × 104, 0.54 × 104 and 0.45 × 104 M?1 respectively for compounds 1f, 1h, 1i. The compounds were cytotoxic to almost every cell line (PC3, HeLa, A549, HCT116) tested, having minimal toxicity in normal NKE cell line, among which PC3 cells were more sensitive with an IC50 value of 10 μM. The values were determined using dose response curve and found between 10 and 49 μM for cancer cells and 70 μM for normal cell. Compounds also cause apoptosis in PC3 cells, which was confirmed by Annexin V-FITC/PI assay. Results showed that 1f, 1h, 1i target DNA, to persuade DNA damage mediated cancer cell death. The inhibition zone was formed in the screening test indicating the anti-bacterial activity of 1f, 1h & 1i against model pathogenic bacteria. So the present communication provides quantitative insight of halo-chalcone based anti-cancerous and antimicrobial molecule involving relevant target nucleic acid, which holds future promise in the development of new therapeutic agents.

Evaluation of novel chalcone-thiosemicarbazones derivatives as potential Anti-leishmania amazonensis agents and its HSA binding studies

Mendes, Edinéia Pastro,Goulart, Carla Marins,Chaves, Otávio Augusto,Fai?es, Viviane Dos S.,Canto-Carvalho, Marilene M.,Machado, Gerzia C.,Torres-Santos, Eduardo Caio,Echevarria, Aurea

, (2019)

A series of seven chalcone-thiosemicarbazones (5a–5g) were synthesized and evaluated as potential new drugs (anti-leishmanial effect). Although four of the chalcone-thiosemicarbazones are already known, none of them or any compound in this class has been previously investigated for their effects on parasites of the Leishmania genus. The compounds were prepared in satisfactory yields (40–75%) and these compounds were evaluated against promastigotes, axenic amastigotes and intracellular amastigotes of L. amazonensis after 48 h of culture. The half maximal inhibitory concentration (IC50) values of the intracellular amastigotes were determined to be in the range of 3.40 to 5.95 μM for all compounds assayed. The selectivity index showed value of 15.05 for 5a, whereas pentamidine (reference drug) was more toxic in our model (SI = 2.32). Furthermore, to understand the preliminary relationship between the anti-leishmanial activity of the chalcone-thiosemicarbazones, their electronic (σ), steric (MR) and lipophilicity (π) properties were correlated, and the results indicated that moieties with electronic withdrawing effects increase the anti-leishmanial activity. The preliminary pharmacokinetic evaluation of one of the most active compound (5e) was studied via interaction to human serum albumin (HSA) using multiple spectroscopic techniques combined with molecular docking. The results of antiparasitic effects against L. amazonensis revealed the chalcone-thiosemicarbazone class to be novel prototypes for drug development against leishmaniasis.

Palladium-Catalyzed Synthesis of α-Methyl Ketones from Allylic Alcohols and Methanol

Biswal, Priyabrata,Samser, Shaikh,Meher, Sushanta Kumar,Chandrasekhar, Vadapalli,Venkatasubbaiah, Krishnan

One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.

New nicotinic acid-based 3,5-diphenylpyrazoles: design, synthesis and antihyperlipidemic activity with potential NPC1L1 inhibitory activity

Shoman, Mai E.,Aboelez, Moustafa O.,Shaykhon, Montaser Sh. A.,Ahmed, Sanaa A.,Abuo-Rahma, Gamal El-Din A.,Elhady, Omar M.

, p. 673 - 686 (2020/02/25)

Nicotinic acid hydrazide was incorporated into new 4,5-dihydro-5-hydroxy-3,5-diphenylpyrazol-1-yl derivatives. Compounds 6a–h were synthesized, and their antihyperlipidemic activity was evaluated in high cholesterol diet-fed rat model. Compounds 6e, 6f were found to decrease the levels of serum total cholesterol by 14–19% compared to control group. Total triglycerides were also reduced by 24–28% and LDL cholesterol by 16%. As expected from parent niacin, compounds 6e and 6f caused an elevation of HDL cholesterol by 33–41%. Docking study supported the ability of designed compounds to block NPC1L1 active site in a manner similar to that observed with ezetimibe.

Rapid umpolung Michael addition of isatin N, N ′-cyclic azomethine imine 1,3-dipoles with chalcones

supporting information, p. 11712 - 11718 (2021/07/12)

The umpolung Michael addition of isatin N,N′-cyclic azomethine imine 1,3-dipoles with chalcones is reported. The reaction could be finished within a very short time (0.3-2 min), with 3,3-disubstituted oxindole derivatives obtained in moderate to excellent yields with promising dr values. Unusual Michael adducts were obtained in moderate to high yields (26-98%) with low to high diastereoselectivities (0.8: 1 to 8.5: 1 dr). All the synthesized compounds (3, 3′, 4, 5, 5′, 7, 7′, 9 and 9′) were well characterized by FTIR, NMR, and mass spectral analyses and further confirmed by the single-crystal X-ray diffraction analysis of compounds 3aa and 4n.
