サパラ Product Lineup

In the development of oligonucleotide drugs, precise structural control of the backbone will be the key to the next generation. Sapala Organics proposes the "C5'-extended 2'-substituted phosphoramidite" to overcome this challenge. Features of C5'-extended 2'-substituted phosphoramidite: The most significant feature of this product is that it physically extends the "distance" between nucleotides by elongating the C5' position. This allows for the resolution of steric hindrance that was difficult to avoid with conventional nucleic acid structures and enables optimal orientation control towards target molecules. Furthermore, a diverse range of modifications such as H, OMe, MOE, and F are available at the 2' position, supporting the advanced coexistence of nuclease resistance and binding affinity.

"Three Innovations Brought by 4'-Thio Modification" 1. Excellent Nuclease Resistance (Approximately 600 Times Higher than Natural) 4'-thioRNA has a structure in which the oxygen at the 4' position of the ribose ring is replaced by sulfur. This slight change creates stability. 2. Strong and Accurate Hybridization Ability In addition to stability, the binding strength to the target (Tm) is also enhanced, which is a strength of 4'-thio. - Increase in Tm: An increase of approximately 1°C in Tm is expected per modification, providing a stabilization effect comparable to that of 2'-O-methyl modifications. - Maintenance of A-type Structure: By inducing the sugar moiety into an RNA-like "C3'-endo conformation," it improves thermal stability while maintaining a structure close to natural RNA. 3. Compatible with Existing Platforms Despite being a new technology, its low introduction cost is a significant advantage. - Standard Synthesis Method: Supplied in DMTr-protected and phosphoramidite form, it can be used directly with your existing automated synthesizers. - Smooth Transition: Base protection uses standard methods (such as Bz, iBu), allowing the deprotection and purification processes to be optimized based on existing protocols.

We are pleased to introduce a groundbreaking building block series, "3'-Azidomethyl-2'-deoxy-nucleosides" (dA, dG, dC, dU), that will accelerate your company's next-generation nucleic acid drug development program. The key feature of this strategic material is the unique azidomethyl group at the 3' position of deoxyribose. This structure provides a powerful advantage that is not found in conventional modified nucleosides. - Utilization and Three Powerful Advantages Here are three powerful advantages gained by utilizing this reagent: 1) High-efficiency functionalization (click chemistry) 2) Improved stability and persistence 3) Chain terminator

This novel nucleoside building block offers excellent advantages compared to conventional reagents with protective groups, as outlined below. 1. Extremely mild deprotection conditions - Conventional deprotection: In standard oligonucleotide synthesis, harsh conditions such as treatment with concentrated ammonia or high temperatures were required to cleave the oligomer from the support and remove protective groups (especially acyl protecting groups like benzoyl or isobutyryl). These conditions could damage unstable sequences, such as modified nucleosides or long-chain oligonucleotides. - Acetoxime protecting group: The 3'-acetoxime protecting group can be rapidly removed under extremely mild conditions, such as treatment at room temperature with water or weakly basic buffers (e.g., triethylammonium carbonate at pH 7-8). This dramatically improves purity and yield in the synthesis of complex probes and drugs, particularly those containing molecules sensitive to heat or bases (e.g., fluorescent dyes, thiolate modifications). 2. Reduction of synthesis cycle time Mild deprotection conditions shorten the overall time of the synthesis process.
