Sometimes, it can be challenging to control the PSD to the target value via optimization of the crystallization process alone; in these scenarios, high shear wet milling is often utilized to reduce PSD. Much work has been done developing scaling parameters to be able to robustly scale-up wet milling processes and consistently achieve target PSD at the plant/commercial scale. While different scaling parameters have had good success with guiding scale-up of terminal wet milling processes, wet milling while crystallization is ongoing (i.e., integrated crystallization and wet milling; iCWM) introduces additional complexity to the system, as it couples scale-independent growth with scale-dependent milling and is therefore more difficult to scale-up in a reproducible manner. Herein, we present how population balance modeling of an iCWM process indicated that mill size and batch size, in addition to wet mill tip speed, had a large impact on final PSD. The model predictions can be used to guide selection of wet mill tip speed in order to maintain consistent PSD across different batch sizes and mill sizes.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"6 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142833007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the latest surge in development, they are paving the way to the market at a rapid pace. To support that, scalable and economically sustainable oligonucleotide production is required. The upstream part exploits the well-studied phosphoramidite chemistry, known from the 1960s, using automated synthesis on a solid support. On the other hand, the downstream processing, which consists of purification and isolation steps, has stayed in the shadow of the more thoroughly studied synthesis, even though it is often regarded as the bottleneck of therapeutic oligonucleotide production. Therefore, this review aims to highlight the most important traditional purification and isolation approaches for the production of therapeutic oligonucleotides that ensure product quality, yields, scale, and cost-efficiency as well as newly emerging separation technologies that could become relevant in the future.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"1 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142833006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a point of reference, this study included phosphines that have previously been documented in the literature [4-diphenylphosphino benzoic acid (DPPBA), tris(3-sulfophenyl)phosphine (TSPP), and 3-(diphenylphosphino)benzenesulfonate (diPPBS)]; however, all known reductants showed the formation of undesired side products upon reduction (detectable by IEX), especially at higher phosphine loadings. The high-throughput study also revealed several phosphines with potential for selective reduction that had not been previously studied for this type of transformation. These initial hits were further evaluated with regard to the phosphine/mAb ratio, solubility in aqueous media, and air oxidation behavior. The best phosphine identified (1-(4-(diphenylphosphanyl)benzyl)-1-methylpyrrolidin-1-ium bromide (<b>P10</b>)) was then employed in a sequence of high-throughput studies that established efficient one-pot reduction/conjugation reaction conditions.

As a common factor involved in the formation and contamination of nitrosamines, we focused on the extremely small amount of nitrogen oxides in the air and searched for ways to reduce them. As a result, we found that the chemical filter cartridges (made by NIPPON MUKI Co., Ltd.) decreased nitrogen oxides from the tens of parts per billion level to the several ppb levels. We expect that our finding will be used as one useful strategy to control the nitrosation caused by repeated exposure of the drug substances and drug products to small amounts of nitrogen oxides during processing and lead to the supply of safe and reliable pharmaceutical products.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"29 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Food and Drug Administration’s Process Analytical Technology (PAT) initiative offers a platform to implement advanced methods to improve the efficiency and understanding of pharmaceutical manufacturing processes and shows great promise in application toward industrial SPPS. In this work, Raman spectroscopy was used as the main PAT tool to implement methods for on-line and real-time monitoring of the entire SPPS process, from Fmoc removal, to coupling, and through the extensive solvent-washing steps. Raman spectroscopy is a rapid, specific, and nondestructive technique that can provide rich real-time information for SPPS processes and can be used to improve efficiency in solvent use and save process time. Specifically, this work reports on the development of PAT methods for monitoring of amino acid coupling during the coupling stage and residual piperidine concentration during the post-deprotection washing stage of SPPS, to help reduce solvent use and better understand the coupling reaction and its time frame. We show a significant reduction in solvent use is possible by employing Raman spectroscopy along with a partial least squares model to predict the piperidine concentration in real time during continuous wash. In addition, Raman spectroscopy offers a greater understanding of coupling reaction kinetics during SPPS, which could lead to significant improvements in total SPPS process time.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"21 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
