Abstract - One of the most significant processes for creating carbon-carbon bonds in organic synthesis is the Mannich reaction. It offers amino carbonyl compounds, crucial synthetic building blocks for many medicines. This Mannich bases are made by combining primary and/or secondary amines, formaldehyde, and active hydrogen molecules. Among those that are active hydrogen compounds include an acid, phenol, ketone, amide, etc. contribution involved the synthesis of 3,5 dimethyl carboxamide using a number of biologically active sulphonamides, which was followed by analysis of elements and spectru

Background: Phenolic Mannich bases have been reported as acetylcholinesterase (AChE) inhibitors for the medication of Alzheimer's disease. Carbonic Anhydrases (CAs) are molecular targets for anticonvulsant, diuretic and antiglaucoma drugs in the clinic. Phenolic compounds have also been mentioned as CA inhibitors. The importance of Mannich bases in drug design inspired our research group to design novel phenolic Mannic bases as potent enzyme inhibitors.

Mannich bases are the end products of Mannich reaction and are known as beta-amino ketone carrying compounds. Mannich reaction is a carbon-carbon bond forming nucleophilic addition reaction and is a key step in synthesis of a wide variety of natural products, pharmaceuticals, and so forth. Mannich reaction is important for the construction of nitrogen containing compounds. There is a number of aminoalkyl chain bearing Mannich bases like fluoxetine, atropine, ethacrynic acid, trihexyphenidyl, and so forth with high curative value.

Abstract:
The year 2025 marks a decade since the U.S. Supreme Court legalized marriage for same-sex couples nationwide. Using the American Community Survey, 2023 1-year estimates from IPUMS USA (Ruggles et al., 2024), we present updated national estimates of individuals entering into same-sex and different-sex marriages in the last year (newlywed couples), building on our earlier profiles based on 2019 (Payne &amp; Manning, 2021) and 2022 data (Westrick-Payne &amp; Manning, 2023). We compare same-sex and different-sex newlyweds by marital history, average age at most recent marriage, and age gap between

Abstract:
In 2022, approximately 60.5 million adults aged 50 and older were grandparents, according to the Survey of Income and Program Participation (SIPP, 2023). The SIPP is a nationally representative household-based survey and is designed to provide comprehensive family and social information on individuals and families. The SIPP gathers information on all individuals who live in a surveyed household and directly asks respondents if they are a grandparent. For these reasons, SIPP is one of the few surveys that identifies non-resident grandparents. In this profile, we identify the prevalence of grand

Abstract:
In 2022, there were more than 64 million grandparents aged 40 and older in the United States, according to the Survey of Income and Program Participation (SIPP, 2023). This figure represents 40% of adults aged 40 and older. The SIPP is a nationally representative household-based survey and is designed to provide comprehensive family and social information on individuals and families. Because the SIPP gathers information on all individuals who lived in a surveyed household, and directly asks respondents if they are a grandparent, it is one of the few surveys that identifies both non-resident an

Abstract:
June 26, 2025 marks the tenth anniversary of Obergefell v. Hodges, the Supreme Court ruling that the right to marry is guaranteed to couples of the same sex by the Fourteenth Amendment. Marking this landmark decision, we present an updated demographic portrait of marriages to same-sex and different-sex couples with 2023 data from the American Community Survey 1-year PUMS files. We begin with an overview of married couples followed by comparisons of individuals in same-sex married couples with those in different-sex married couples based on their marital history, age, education and race/ethnici
